Nuclear pairing from bare interaction: Two and three-body chiral forces.

In a recent paper [1] the ¹S₀ pairing gap in isospin-symmetric nuclear matter and finite nuclei has been investigated starting from the chiral nucleon-nucleon potential at the N³LO order in the two-body sector and the N²LO order in the three-body sector. To include realistic nuclear forces in RHB (Relativistic Hartree Bolgoliubov) calculations we relied on a separable representation of the pairing interaction. In this paper we would like to show recent results concerning isotonic chains with N = 28,50,82. [ABSTRACT FROM AUTHOR]
