Mass Dependence Of The Landau-Migdal Parameter Estimated With Effective Interactions

Abstract

In this paper, the mass dependence of the Landau-Migdal parameter g'_NN(A) is investigated. This investigation requires three stages: In the first stage, we derive an effective interaction using the method of the lowest - order constrained variational (LOCV) approach with two-body correlation functions based on the Nijmegen potential. In the second stage, we have separated the matrix elements of the effective two-body potential into those of the various channels. These are the singlet-even (SE), the singlet-odd (SO), the triplet-even (TE) and the triplet-odd (TO) channels needed to compute the Landau-Migdal parameter. In the final stage we computed the Landau-Migdal parameter g'_NN(A), as a function of the mass number, A.
