Analysis of shape isomer yields of heavy elements in the framework of dynamical-statistical model

Abstract

Experimental data on shape isomer yield for α + 239 Pu reaction at E α lab = 20 – 29 MeV are analyzed in the framework of the combined dynamical statistical model. The possibility of determining the double humped fission barrier parameters are discussed for some Cm isotopes and it is shown that the depth of the second potential well should be smaller than the results of statistical model calculations.
