Purpose: In this paper, for the system 48Ca +27 Al at 40 MeV/nucleon, we investigate on this process by means of an observable tightly linked to isospin equilibration processes and sensitive in exclusive way to the dynamical stage of the collision. From the comparison with dynamical model calculations we want also to obtain information on the Iso-vectorial effective microscopic interaction. Method: The average time derivative of the total dipole associated to the relative motion of all emitted charged particles and fragments has been determined from the measured charges and velocities by using the 4? multi-detector CHIMERA. The average has been determined for semi- peripheral collisions and for different charges Zb of the biggest produced fragment. Experimental evidences collected for the systems 27Al+48Ca and 27Al+40Ca at 40 MeV/nucleon used to support this novel method of investigation are also discussed. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1501.00801v1-abstract-full').style.display = 'none'; document.getElementById('1501.00801v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 5 January, 2015; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> January 2015. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">Submitted for publication on Phys.

All these effects support the concept of isospin "migration", that is sensitive to the density gradient between participant and quasi-spectator nuclear matter, in the so called neck fragmentation mechanism. By comparing the data to a Stochastic Mean Field (SMF) simulation we show that this method gives valuable constraints on the symmetry energy term of nuclear equation of state at subsaturation densities. An indication emerges for a linear density dependence of the symmetry energy. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('1206.0697v1-abstract-full').style.display = 'none'; document.getElementById('1206.0697v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 4 June, 2012; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> June 2012. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">17 pages, 7 figures; submitted to Physical Rev.

Peaks, originating from resonance decays, are larger at E/A = 44 than at 77 MeV. This reflects the larger relative importance of independently emitted light particles, as compared to two-particle decay from unstable fragments, at the higher beam energy. The time sequence of the light charged particles, emitted from the PLF, has been deduced from particle-velocity-gated correlation functions (discarding the contribution from resonance decays).

Inclusive data were also taken in order to determine the partial wave distribution of the fusion process. The fragment-fragment correlation data show that the majority of events arises from a binary-decay process with a relatively large multiplicity of secondary light-charged particles emitted by the two primary excited fragments in the exit channel. No evidence is observed for ternary-breakup processes, as expected from the systematics recently established for incident energies below 15 MeV/nucleon and for a large number of reactions. The binary-process results are compared with predictions of statistical-model calculations. The calculations were performed using the Extended Hauser-Feshbach method, based on the available phase space at the scission point of the compound nucleus. This new method uses temperature-dependent level densities and its predictions are in good agreement with the presented experimental data, thus consistent with the fusion-fission origin of the binary fully-damped yields. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('nucl-ex/9804004v1-abstract-full').style.display = 'none'; document.getElementById('nucl-ex/9804004v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 30 April, 1998; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> April 1998. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">30 pages standard REVTeX file, 10 eps Figures; to be published at the European Physical Journal A - Hadrons and Nuclei</span> </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/nucl-ex/9803005">arXiv:nucl-ex/9803005</a> <span> [<a href="https://arxiv.org/pdf/nucl-ex/9803005">pdf</a>, <a href="https://arxiv.org/ps/nucl-ex/9803005">ps</a>, <a href="https://arxiv.org/format/nucl-ex/9803005">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Nuclear Experiment">nucl-ex</span> </div> </div> <p class="title is-5 mathjax"> Spin-Alignment and Quasi-Molecular Resonances in Heavy-Ion Collision </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/nucl-ex?searchtype=author&query=Nouicer%2C+R">R.

In the $^{28}$Si~$+$~$^{28}$Si reaction, the resonant behavior of the $^{28}$Si $+$ $^{28}$Si exit-channel is clearly observed by the present fragment-fragment coincidence data. The more unexpected result is the spin disalignment of the $^{28}$Si $+$ $^{28}$Si resonance. This has been demonstrated first by the measured angular distributions of the elastic 0$^{+}$, inelastic 2$^{+}$ and mutual excitation channels 2$^{+}-2^{+}$, which are dominated by a unique and pure partial wave with L = 38 ${\rm \hbar}$, and has been confirmed by measuring their particle-$纬$ angular correlations with Eurogam Phase II. The spin disalignment supports new molecular model predictions, in which the observed resonance would correspond to the ''Butterfly mode''.

Charge distributions, inclusive energy spectra, and angular distributions have been obtained for the evaporation residues and the binary fragments. Angle-integrated cross sections have been determined for evaporation residues from both the complete and incomplete fusion mechanisms. Energy spectra for binary fragment channels near to the entrance-channel mass partition are characterized by an inelastic contribution that is in addition to a fully energy damped component. The fully damped component which is observed in all the binary mass channels can be associated with decay times that are comparable to, or longer than the rotation period. The observed mass-dependent cross sections for the fully damped component are well reproduced by the fission transition-state model, suggesting a fusion followed by fission origin. The present data cannot, however, rule out the possibility that a long-lived orbiting mechanism accounts for part or all of this yield. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('nucl-ex/9711005v1-abstract-full').style.display = 'none'; document.getElementById('nucl-ex/9711005v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 17 November, 1997; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> November 1997. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">41 pages standard REVTeX file, 14 Figures available upon request --</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Journal ref:</span> Phys.Rev.C57:731-742,1998 </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/nucl-ex/9711002">arXiv:nucl-ex/9711002</a> <span> [<a href="https://arxiv.org/pdf/nucl-ex/9711002">pdf</a>, <a href="https://arxiv.org/ps/nucl-ex/9711002">ps</a>, <a href="https://arxiv.org/format/nucl-ex/9711002">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Nuclear Experiment">nucl-ex</span> </div> </div> <p class="title is-5 mathjax"> Fission Fragment Spectroscopy on a $^{28}$Si+$^{28}$Si Quasimolecular Resonance </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/nucl-ex?searchtype=author&query=Nouicer%2C+R">R.

In the $^{28}$Si + $^{28}$Si exit-channel, the resonance behavior of the $^{28}$Si + $^{28}$Si reaction at the beam energy is clearly confirmed. An unexpected spin disalignment has been observed in the measured angular distributions in the elastic, inelastic, and mutual excitation channels. This disalignment is found to be consistent with particle-$纬$ angular correlations and supported by the molecular model prediction of a "butterfly motion". The K$^蟺$ = 0$^{+}_{3}$ band corresponding to the large prolate deformation of the $^{28}$Si is more intensely fed in the resonance region. The selective population of high-excited states are discussed within a statistical fusion-fission model.

The bombarding energy E_{lab}(^{28}Si) = 111.6 MeV has been chosen to populate a well known quasi-molecular resonance in ^{56}Ni. Evidence is presented for a selective population of states in ^{28}Si fragments arising from the symmetric-fission of the ^{56}Ni compound nucleus. In the resonant region the enhanced population of the K^蟺 = 3_{1}^{-} band of the ^{28}Si nucleus, indicative of an oblate deformed shape, appears to play a significant role in the collision processes. The resonant behavior in the elastic and inelatic ^{28}Si+^{28}Si exit-channels is found to be correlated to strong disalignment features of the di-nuclear oblate-oblate system with an equator-equator stable configuration. <a class="is-size-7" style="white-space: nowrap;" onclick="document.getElementById('nucl-ex/9708004v1-abstract-full').style.display = 'none'; document.getElementById('nucl-ex/9708004v1-abstract-short').style.display = 'inline';">△ Less</a> </span> </p> <p class="is-size-7"><span class="has-text-black-bis has-text-weight-semibold">Submitted</span> 8 August, 1997; <span class="has-text-black-bis has-text-weight-semibold">originally announced</span> August 1997. </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Comments:</span> <span class="has-text-grey-dark mathjax">16 pages LaTeX, 9 Figures available upon request</span> </p> <p class="comments is-size-7"> <span class="has-text-black-bis has-text-weight-semibold">Report number:</span> IReS-97-22 (IReS Strasbourg and Louis Pasteur University) </p> </li> <li class="arxiv-result"> <div class="is-marginless"> <p class="list-title is-inline-block"><a href="https://arxiv.org/abs/nucl-ex/9608003">arXiv:nucl-ex/9608003</a> <span> [<a href="https://arxiv.org/pdf/nucl-ex/9608003">pdf</a>, <a href="https://arxiv.org/ps/nucl-ex/9608003">ps</a>, <a href="https://arxiv.org/format/nucl-ex/9608003">other</a>] </span> </p> <div class="tags is-inline-block"> <span class="tag is-small is-link tooltip is-tooltip-top" data-tooltip="Nuclear Experiment">nucl-ex</span> </div> <div class="is-inline-block" style="margin-left: 0.5rem"> <div class="tags has-addons"> <span class="tag is-dark is-size-7">doi</span> <span class="tag is-light is-size-7"><a class="" href="https://doi.org/10.1007/s002180050138">10.1007/s002180050138 <i class="fa fa-external-link" aria-hidden="true"></i></a></span> </div> </div> </div> <p class="title is-5 mathjax"> Statistical Binary Decay of $^{35}$Cl + $^{24}$Mg at 8 MeV/nucleon </p> <p class="authors"> <span class="search-hit">Authors:</span> <a href="/search/nucl-ex?searchtype=author&query=Nouicer%2C+R">R.
