Abstract：
Under the framework of the Bakamjian-Thomas theory,we discuss the qualitativeproperties of the phenomenological nuclear force V= V_R- iV₁at high energy arediscussed by a comparision with the small angle scattering data.Because these data inhigh energy are insensitive to the spin,we suppose that the nuclear force at highenergies is spin-independent.The followings are obtained:i)for the Gaussian potential, X ₃≌200 MeV and β ₃≌0.95 fm,which are thestrength and the range of V₁respectively;ii)in V_R,there is no hard repulsive core.Under a rough estimation,supposingthe range β ₁>0.45 fm,we find the strength of the repulsive force, X ₁<480 MeV;iii)all parameters are vary very slowly with energy.
