TL;DR
This paper solves the ab initio gap equation for neutron pairing in a nuclear slab using the Argonne v18 potential, comparing results with the Paris potential and analyzing the gap's dependence on chemical potential.
Contribution
It provides a detailed comparison of pairing gaps obtained with Argonne v18 and Paris potentials in a nuclear slab, highlighting a 10% difference.
Findings
The pairing gap differs by about 10% between the two potentials.
The gap's dependence on chemical potential is analyzed.
The ab initio approach confirms the robustness of the pairing gap calculation.
Abstract
Ab initio gap equation for ^1S_0 pairing in a nuclear slab is solved for the Argonne v18 NN-potential. The gap function is compared in detail with the one found previously for the separable form of the Paris potential. The difference between the two gaps turned out to be about 10%. Dependence of the gap on the chemical potential mu is analyzed.
