A model for a description of various fission fragment characteristics is proposed. The both nascent fission fragments consist of either the single-body or the two-body systems. The one-body fragment is a single nucleus, while the two-body fragment is

The characteristics of fission fragments of various highly-excited nuclei with 119 ≤ A ≤ 218 , which are formed by γ - and α -captures, and by fusion–fission reactions, are discussed in details. The yields of fission fragments of these nuclei

It is shown that the potential energy surface of the two separated fragments has the saddle point, which takes place at small distance between the surfaces of well-deformed fragments. The height of this two-body saddle point is larger than the height

Simple relations for a calculation of the barrier height B, radius R and curvature $ \hbar \omega$ parameters used in the Wong formula for an evaluation of the heavy-ion fusion cross section are presented. These relations are obtained by a fitting of

The ratio $\Gamma_{{\rm n}}(E)/\Gamma_{{\rm f}}(E)$ is calculated using different expressions for the fission width, which take into account and ignore the dependence of the fission barrier on the excitation energy. A strong influence of the energy-d

A simple expression for the fission width of excited nuclei with the fission barrier dependent on excitation energy is obtained. This fission width is larger than the one obtained with the help of the energy-independent fission barrier. The ratio of

Simple approach is used to a description of the experimental data for the widths of fission fragment mass yields in 197Au and 209Bi at low and intermediate energies. This approach based on both the expression for the temperature dependence of the wid

Simple expression for the temperature dependence of the width of fission-fragment mass yields is obtained for high excitation energies. The width depends on the number of nucleons in nuclei, the volume and surface terms of the energy level density pa
