Энергия возбуждения составных ядер для всех реакций составляла 21±2 МэВ. Эксперименты выполнены на изохронном циклотроне У-150М Института ядерной физики, г. Алматы. Показано, что поведение массовых распределений Y(m) зависит, в основном, от числа протонов в образующихся тяжелом и легком осколках. Для изотопов одного элемента (237,240,242 Pu) зарядовые распределения осколков Y(Z) практически совпадают. Обнаруженные отличия в поведении выходов масс осколков Y(m) от их энергетических распределений (Ek(m) и σ2(m)) указывают на то, что эти характеристики формируются на разных стадиях процесса деления. Кинетическаятэнергия осколков определяется условиями в точке разрыва ядра, массовые распределения формируются на болеетранних стадиях процесса разделения ядра, где будущие осколки еще соединены толстой шейкой.</p></abstract><trans-abstract xml:lang="en"><p>The experimental data on mass and energy distributions of fission fragments of compound nuclei 236U, 237, 240, 242Pu, 244Cm formed in 232Th (α, f), 233, 236, 238U (α, f) и 240Pu (α, f) reactions at incident alpha particle energies of Eα = 29 MeV is presented. Excitation energy of the compound nuclei for all reactions was 21±2 MeV. Experiments were carried on the isochronous cyclotrone U-150M at The Institute of Nuclear Physics, Almaty city.тIt was shown that behavior of mass distributions Y(m) depends mainly on proton number in heavy and light fragmentsтthat are being formed. For isotopes of one element (237, 240, 242 Pu) charge distributions ofтfragments Y(Z) are almost the same. The discovered differences between behaviors of fragments mass distributions Y(m) and their energy distributions (Ek(m) и σ2(m)) points to these characteristics being formed at a different stages of fission process. Kinetic energy is determined by the conditions at rupture point, mass distributions are formed at earlier stages of fission process, when future fragments are still connected by a thick neck.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gönnenwien F.
