Description
The quasi-fission is a nuclear process, realized in the massive nuclei collisions. The quasi-fission is a dominating channel in the reactions of the superheavy elements synthesis, reducing by several orders the cross section for the composite nucleus formation. The concept of the binary nuclear system makes it possible to describe the competition between the channels of the nuclei complete fission and quasi-fission and reproduce the experimental cross sections of the heavy and superheavy elements formation, as well as to interpret the shell effects in the mass distribution of the quasi-fission products
Abstract (Russian)
Квазиделение - ядерный процесс, реализующийся в столкновениях массивных ядер. Квазиделение - доминирующий канал в реакциях синтеза сверхтяжелых элементов, на порядки понижающий сечение образования составного ядра. Концепция двойной ядерной системы позволяет описать конкуренцию между каналами полного слияния ядер и квазиделения и воспроизвести экспериментальные сечения образования тяжелых и сверхтяжелых элементов, а также интерпретировать оболочечные эффекты в массовом распределении продуктов квазиделенияAdditional details
