Seminar topic: “Fission hindrance in even-Z nuclei within DNS model “

Speaker: I. S. Rogov

Abstract:

Half-lives of spontaneous fission and alpha-decay for even-odd isotopes of Cm, Fm and Rf were calculated within the dinuclear system model and compared with the existing experimental data. Both the processes were considered as the evolution of a parent nucleus in the charge asymmetry coordinate and in the relative distance between the centres of clusters formed. The important role of the rotational term of the total potential energy in the charge asymmetry coordinate are elucidated and the origin of the fission hindrance is explained.
