Abstract：
The behavior of the phase-shift of the Bakamjian-Thomas theory and its relationwith the phenomenological nuclear force V= V _R iV _Iat high energy are explored.Two limits are obtained: It is found that the repulsive core with a sharp outer edge may induce a characteris-tic oscillation of Re δ ₁,and Im δ ₁is sensitive to V ₁.The conclusion is that the analy-sis of the phase-shift extending to higher energy is relevant in determining therepulsive core and the imaginary part of the nuclear force.
