Аннотация
The production of residual nuclei in the reactions ${}^{25}$Mg + ${}^{206}$Pb, ${}^{36}$S + ${}^{\mathrm{nat}}$Pt, and ${}^{48}$Ca + ${}^{\mathrm{nat}}$W was investigated at low bombarding energies at the velocity filter SHIP (GSI, Darmstadt). The data are discussed within the dinuclear system model. In particular, the emission of complex fragments with $Z>2$ from heavy compound nuclei is treated within the model and supported by the experimental data. The production channels and cross sections, charge, and isotopic distributions of the residual heavy nuclei are presented.
