halides such as, NaCl, KCl, CuCl, NaBr, KBr, RbCl, AgCl, NaI, KI, AgBr, CsI, HgCl<sub>2</sub>, CdI<sub>2</sub> and HgI<sub>2</sub> were determined at photon energies 279.2, 320.07, 514.0, 661.6, 1115.5, 1173.2 and 1332.5 keV in a well-collimated narrow beam good geometry set-up using a high resolution, hyper pure germanium detector. The mass attenuation coefficients and the effective atomic cross sections are found to be in good agreement with the XCOM values. From these mass attenuation coefficients, the effective atomic cross sections s<sub>a,</sub> of the compounds were determined. These effective atomic cross section s<sub>a</sub> data so obtained are then used to compute the effective atomic numbers Z<sub>eff</sub>. For this, the interpolation of total attenuation cross-sections of photons of energy E in elements of atomic number Z was performed by using the logarithmic regression analysis of the data measured by the authors and reported earlier for the above said energies along with XCOM data for standard energies. The best-fit coefficients in the photon energy range of 250 to 350 keV, 350 to 500 keV, 500 to 700 keV, 700 to 1000 keV and 1000 to 1500 keV by a piecewise interpolation method were then used to find the Z<sub>eff</sub> of the compounds with respect to the effective atomic cross section s<sub>a</sub> from the relation obtained by piece wise interpolation method. Using these Z<sub>eff</sub> values, the electron densities N<sub>el</sub> of halides were also determined. The present Z<sub>eff</sub> and N<sub>el</sub> values of halides are found to be in good agreement with the values calculated from XCOM data and other available published values. <iframe src="https://publications.waset.org/10005210.pdf" style="width:100%; height:400px;" frameborder="0"></iframe> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Mass%20attenuation%20coefficient" title="Mass attenuation coefficient">Mass attenuation coefficient</a>, <a href="https://publications.waset.org/search?q=atomic%20cross-section" title=" atomic cross-section"> atomic cross-section</a>, <a href="https://publications.waset.org/search?q=effective%20atomic%20number" title=" effective atomic number"> effective atomic number</a>, <a href="https://publications.waset.org/search?q=electron%20density." title=" electron density."> electron density.</a> </p> <p class="card-text"><strong>Digital Object Identifier (DOI):</strong> <a href="https://doi.org/10.5281/zenodo.1126121" target="_blank">doi.org/10.5281/zenodo.1126121</a> </p> <a href="https://publications.waset.org/10005210/the-mass-attenuation-coefficients-effective-atomic-cross-sections-effective-atomic-numbers-and-electron-densities-of-some-halides" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/10005210/apa" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">APA</a> <a href="https://publications.waset.org/10005210/bibtex" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">BibTeX</a> <a href="https://publications.waset.org/10005210/chicago" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Chicago</a> <a href="https://publications.waset.org/10005210/endnote" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">EndNote</a> <a href="https://publications.waset.org/10005210/harvard" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">Harvard</a> <a href="https://publications.waset.org/10005210/json" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">JSON</a> <a href="https://publications.waset.org/10005210/mla" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">MLA</a> <a href="https://publications.waset.org/10005210/ris" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">RIS</a> <a href="https://publications.waset.org/10005210/xml" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">XML</a> <a href="https://publications.waset.org/10005210/iso690" target="_blank" rel="nofollow" class="btn btn-primary btn-sm">ISO 690</a> <a href="https://publications.waset.org/10005210.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">2122</span> </span> <p class="card-text"><strong>References:</strong></p> <br>[1] D.F.
