Annotation

A dynamical-statistical model is used to analyze the experimental angular distributions of fission fragments in the reactions $\alpha+{}^{238}$U, $^{237}$Np at $E_\alpha=(20\div100)$ MeV, as well as to determine the Am isotope fission probabilities and the shape isomer yields in the reactions $d+{}^{242,240}$Pu at $E_d=(20\div30)$ MeV. Manifestations of shell effects are found in the fission barrier structure up to the excitation energies of $(50\div60)$ MeV.
