Description
The calculations of probability for formation of a composite nucleus in the reactions of cold synthesis of the 104-114 elements and hot synthesis of the 110, 112 and 114 elements are carried out within the frames of the concept of the binary nuclear system and the completion model for complete fusion and quasi-fission. It is shown, that the quasi-fission is the main factor of the cross section decrease during heavy element formation with growth of its atomic number. The calculations of the minimum excitation energy of the composite nuclei by the cold synthesis of the 102-114 elements are carried out
Abstract (Russian)
В рамках концепции двойной ядерной системы и модели конкуренции полного слияния и квазиделения проведены расчеты вероятности формирования составного ядра в реакциях холодного синтеза 104-114-го элементов и теплого синтеза 110, 112 и 114-го элементов. Показано, что квазиделение является главным фактором снижения сечения образования тяжелего элемента с ростом его атомного номера. Проведены расчеты минимальной энергии возбуждения составных ядер при холодном синтезе 102-114-го элементовAdditional details
