Semi-realistic nucleon-nucleon interactions with improved neutron-matter
properties    [PDF]

H. Nakada

New parameter-sets of the semi-realistic nucleon-nucleon interaction are developed, which are applicable to the self-consistent mean-field (both Hartree-Fock and Hartree-Fock-Bogolyubov) calculations, by modifying the M3Y interaction. The modification is made so as to reproduce microscopic results of neutron-matter energies, in addition to the measured binding energies of doubly magic nuclei including $^{100}$Sn, and the even-odd mass differences of the Z=50 and N=82 nuclei. With the new parameter-sets M3Y-P6 and P7, the spin-saturated symmetric nuclear matter remains stable in the density range as wide as $\rho\lesssim 6\rho_0$. Separation energies of the proton- or neutron-magic nuclei are shown to be in fair agreement with the experimental data.
