Gogny force with a finite-range density dependence

Abstract: In the present work, we have investigated an extension of the effective nucleon-nucleon Gogny interaction in which the zero-range density-dependent term has been replaced with a finite-range term. The parameters have been adjusted on both nuclear-matter properties and a few observables of stable nuclei. The traditional and unified fitting procedure of the Gogny force used in Bruyères-le-Châtel ensures common basic properties between the extended analytical form of the Gogny interaction, called D2, and the orig… Show more

“…Recent multiparticle-multihole configuration mixing studies [12,13] have motivated the elaboration of a generalized Gogny interaction with finite-range density, spin-orbit and tensor terms. Along that line, Gogny D2 interaction with a finite range density term has been designed [14]. The second strategy is more based on brute force using HFB with a self-consistent account of quadrupole correlations energies within the 5DCH approach.…”

“…To this purpose one has to minimize in a multi-dimensional space a penalty function. The latter is obtained by considering some observables of finite nuclei as for example masses and radii and some pseudo-observables of infinite nuclear matter [6][7][8]. The minimization procedure can be quite evolved since the penalty function presents discontinuities in the parameter space and therefore may induce some difficulties in finding a stable minimum.…”

“…Finally, a new interaction named D2, with a finite-range version of the density dependent term has been presented recently in Ref. [39]. Our results can be easily modified to take into account such a new term.…”
