Abstract

The average angular momenta and widths of the spin distributions of reaction products are calculated within the dinuclear system model. The thermal excitation of rotational bearing modes is considered in the dinuclear system. The calculated fragment spins (γ multiplicities) and their variances in the reactions Ne20 (166 MeV) + Cu63, Ar40 (280 MeV) + Ni58, Ne20 (175 MeV) + Agnat, Ar40 (237 MeV) + Y89, Ar40 (288 and 340 MeV) + Ag107,109, and O16 (100 MeV) + Ni58 are compared with the available experimental data. The influence of the entrance channel charge (mass) asymmetry and bombarding energy on the characteristics of spin distribution is studied.
