摘要

Fig.1 shows the impact parameter-averaged asymptotic values of the number of the emitted neutrons N_n and the number of the emitted protons N_p(when the values of N_p and N_n at t=200 fm/c become nearly constants) i.e.b(top window)andb(bottom window)as a function of the beam energy with momentum dependent intraction for the systems~(76)Kr+~(40)Ca(left windows)and ~(76)Kr+~(76)Kr(right windows)in five cases:
