Reaction Matrix Calculations in Neutron Matter with AlternatingLayerSpin Structure under π^{0} Condensation. II Numerical Results
Abstract
Results obtained by applying a formulation based on the reaction matrix theory developed in I are given. Calculations by making use of a modified realistic potential, the Reid softcore potential with the OPEPpart enhanced due to the isobar (∆)mixing, show that the transition to the [ALS] phase of quasineutrons corresponding to a typical π^{0} condensation occurs in the region of (2 ∼ 3) times the nuclear density. The most important ingredients responsible for this transition are the growth of the attractive ^{3}P_{2} + ^{3}F_{2} contribution mainly from the spinparallel pairs in the same leyers and the reduction of the repulsive ^{3}P_{1} contribution mainly from the spinantiparallel pairs in the nearest layers; these mainfest themselves as the [ALS]type localization develops. Properties of the matter under the new phase thus obtained such as the shape of the Fermi surface and the effective mass are discussed.
