Light nuclei production in fusion of heavy ions

A possible mechanism of the production of light nuclei in fusion reactions is considered. It is shown that the decay of the dinuclear system during its evolution to a compound nucleus yields a substantial rate for the production of light nuclei. The cross section of this process is calculated for the reaction ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$${+}^{58}$Ni. The coupling of other modes of motion causes an increase of the asymmetric decay of the dinuclear system.
