A possible mechanism of the production of light nuclei in fusion reactions is considered. It is shovrn 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+ Ni. The coupling of other modes of motion causes an increase of the asymmetric decay of the dinuclear system.

Assuming a binary reaction mechanism, the yield of isotopes near the heaviest $N=Z$ neutron-deficit nucleus $^{100}$Sn is studied with a microscopic transport model. The large influence of nuclear shell structure and isotope composition of the colliding nuclei on the production of exotic nuclei is demonstrated. It is shown that the reaction $^{54}$Fe+$^{106}$Cd seems to be most favourable for producing primary exotic Sn isotopes which may survive if the excitation energy in the entrance reaction channel is less than about 100 MeV. In the case of large differences in the charge (mass) numbers between entrance and exit channels the light fragment yield is essentially fed from the decay of excited primary heavier fragments. The existence of optimal energies for the production of some oxygen isotopes in the binary mechanism is demonstrated for the $^{32}$S+$^{197}$Au reaction.Comment: 17 pages, RevTex, 8 Postscript figures, submitted to Phys.

Abstract. In the single-particle approach a partition of the excitation energy between the reaction products in deep inelastic collisions of heavy ions are investigated. The role of the particle-hole excitations and the nucleon exchange is considered. The ratio of the projectile excitation energy to the total excitation energy for the reactions 238U(1468 MeV)+124Sn, 238U(1398 MeV)+ll~ 56Ee(505 MeV)+ 165Ho, 74Ge(629 MeV)+ 165Ho and 68Ni(880 MeV)+ 197Au is calculated. The results of calculations are in good agreement with the experimental data.

The microscopic treatment of proton and neutron multiple transfer in DIC

Abstract: The proton and neutron transfer in deep-inelastic heavyion collisions (DIC) is investigated in the framework of the microscopical model. It is shown that the isospin dependence of the single-particle potential is important for the correct description of the experimental data.
