FISSION-LIKE AND REACTION-TIME IN 8.5 MEV U KR-84+AL-27 REACTION/

Reaction time of the deeply inelastic reaction in 8.5MeV/u Kr-84+Al-27 was estimated to be 8 x 10(-21) s by extracting pre-scission alpha an d proton multiplicities and by statistical model(PACE4) calculations. By using this reaction time value, the diffusion model calculations fo r the charge number distribution of fragments nicely explained the exp erimental results for the reactions at three incident energies 5.8, 8. 5 and 10.6 MeV/u. It is indicated that a considerable fission-like com ponent has contributed to the symmetric splitting fragments in the rea ctions, especially at 8.5 and 10.6 MeV/u.
