Annotatsiya

A cluster model is applied to the description of the decay out phenomenon of the yrast superdeformed states in the nuclei $^{190,192,194}\mathrm{Hg}$ and $^{192,194,196}\mathrm{Pb}$. The model is based on the assumption that highly deformed cluster-type shapes are produced by a collective motion of the nuclear system in the charge asymmetry coordinate. As follows from our analysis, the sudden transition from the superdeformed minimum to the normal deformed minimum occurs because of the crossing of superdeformed band with the nearest neighboring excited normal deformed band and spreading of collective states among the compound states.
