A possible mechanism of the production of light nuclei in fusion react
ions 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 Ni-58 + Ni-58. The coupling of other mo
des of motion causes an increase of the asymmetric decay of the dinucl
ear system.
