Title: PERTURBATION THEORY IN NUCLEAR MATTER WITH REGULAR BUT VELOCITY DEPENDENT INTERACTIONS

Abstract

Considering regular but velocity-dependent interactions, the direct and exchange terms of the second-order energy for nuclear matter are calculated. A study is made of whether such interactions, which can be fitted to the twobody data, lead to a quickly converging perturbation series. A rather large cortribution from singlet-even states to the direct and exchange term, at densities corresponding to k/sub F/ = 1.5 fm/sup -1/, indicates a very slow convergence even in the absence of a hard-core interaction. This result is partially caused by the short range of the velocitydependent term in the interaction. (auth)
