摘要
Reaction time of the deeply inelastic reaction in 8.5MeV/u ^(84)Kr+^(27)A1 was estimated to be 8×10^(-21)s by extracting pre-scissionαand proton multiplicities and by statistical model(PACE4)calculations.By using this reaction time value,the diffusion model calculations for the charge number distribution of fragments nicely explained the experimental results for the reactions at three incident energies 5.8,8.5 and 10.6MeV/u.It is indicated that a considerable fission-like component has contributed to the symmetric splitting fragments in the reactions,especially at 8.5 and 10.6 MeV/u.
