Asymmetric fission barriers for hot rotating nuclei and experimental mass distributions of fission fragments

Conditional asymmetric fission barriers (barriers at given mass-asymmetry v alues) have been calculated on the basis of the rotating-liquid-drop model that takes into account short-range nuclear forces and the diffuseness of t he nuclear surface. These calculations have been performed for 15 nuclei in the range Z(2)/A = 20-40 for angular-momentum values from 0 to 70 (h) over bar. For any angular-momentum value up to 70 (h) over bar, a direct compar ison of theoretical mass distributions obtained within the statistical appr oach with available experimental data reveals reasonably good agreement in the interval Z(2)/A = 20-30.
