摘要
By using the dinuclear system approach combined with quantum diffusion and statistical methods, the population of the yrast superdeformed band in the Dy-152 nucleus is treated. The excitation functions are calculated and analyzed for the population of the superdeformed states in xn, pxn, and alpha xn evaporation channels of different asymmetric and almost symmetric reactions. The dependencies of the relative intensities of E2 transitions between the rotational states of the superdeformed band on the de-excitation channels, charge asymmetry of the entrance channel, and beam energy are established. The restrictions of the population of the superdeformed band in spin by complete fusion and quasifission processes are shown. The calculated results are compared with the available experimental data.
