Kertas kerja itu tidaklah menekankan kewujudan partikel baru, tetapi membenarkan elektron untuk memiliki tenaga positif dan negatif sebagai penyelesaian. Penyelesaian tenaga positif menjelaskan keputusan eksperimen, tetapi Dirac sendiri bingung dengan penyelesaian tenaga negatif yang sama benar yang dibenarkan model matematik tersebut. Mekanik kuantum tidak membenarkan penyelesaian tenaga negatif untuk diendahkan sepertimana yang dibenarkan oleh mekanik klasik, sebaliknya dua penyelesaian itu menyatakan bahawa ada kemungkinan elektron beralih di antara keadaan tenaga positif dan negatif. Namun, peralihan seperti ini tidak pernah diperhatikan melalui eksperimen. Dirac merujuk kepada konflik antara teori dan pemerhatian ini sebagai "kesulitan" yang belum "diselesaikan". </p><p>Dirac menulis satu kertas kerja sambungan pada Disember 1929 yang telah mencuba untuk menjelaskan penyelesaian tenaga negatif yang tidak dapat dielakkan untuk elektron relativistik. Dia mengatakan "... satu elektron dengan tenaga negatif bergerak di dalam medan [elektromagnet] luaran seolah-olah ia membawa cas positif". Dia juga mengatakan bahawa keseluruhan ruang boleh dianggap sebagai <a href="/w/index.php?title=Laut_Dirac&action=edit&redlink=1" class="new" title="Laut Dirac (laman tidak wujud)">satu "lautan" keadaan tenaga negatif</a> yang telah diisi, sehingga ia menghalang elektron daripada beralih daripada keadaan tenaga positif (cas negatif) dan keadaan tenaga negatif (cas positif). Kertas kerja ini juga meneroka kemungkinan <a href="/wiki/Proton" title="Proton">proton</a> menjadi sebuah "pulau" di dalam laut ini, dan ia berkemungkinan satu elektron bertenaga negatif. Dirac mengakui yang proton mempunyai jisim yang lebih banyak daripada elektron dan ini mendatangkan masalah terhadap jangkaan beliau, tetapi beliau "berharap" teori pada masa akan datang akan menyelesaikan isu ini. </p><p><a href="/wiki/Robert_Oppenheimer" title="Robert Oppenheimer">Robert Oppenheimer</a> telah menentang jangkaan Dirac yang menyatakan penyelesaian tenaga negatif elektron untuk persamaan Dirac ialah proton. Beliau menegaskan yang jika pernyataan ini benar, atom hidrogen pasti akan musnah dengan sendiri dengan pantas. Terdesak oleh hujah Oppenheimer, Dirac menerbitkan satu kertas kerja pada 1931 yang meramalkan kewujudan partikel yang masih belum ditemui pada masa itu, "anti-elektron" yang mempunyai jisim yang sama dengan elektron dan akan musnah habis apabila bertemu dengan elektron. </p> <div class="mw-heading mw-heading3"><h3 id="Klu_eksperimen_dan_penemuan">Klu eksperimen dan penemuan</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Positron&veaction=edit&section=3" title="Sunting bahagian: Klu eksperimen dan penemuan" class="mw-editsection-visualeditor"><span>sunting</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Positron&action=edit&section=3" title="Sunting kod sumber bahagian: Klu eksperimen dan penemuan"><span>sunting sumber</span></a><span class="mw-editsection-bracket">]</span></span></div> <table width="180px" cellpadding="2" style="float: right;
