Abstract:

Several kinds of phase-shift equivalent one-boson-exchange potential (OBEP) including velocity-dependent term are constructed so as to reproduce the two-nucleon data. Here we propose an “extended Green's method” to treat the velocity-dependent tensor potential. Nuclear matter and neutron matter properties are calculated for our ninstatic OBEP. The phase-shift equivalent OBEP's, however, give different nuclear matter properties owing to the difference of the softness of core potential and the retardation. The retardation strengthens the tensor-to-central ratio of OBEP in the triplet even state, and reduces the nuclear matter binding energy per particle by 2.6∼5.0 MeV with a decrease in density by 0.05∼0.08 fm-1. However, the retarded effect on neutron matter is relatively small.
