Abstract
We present preliminary results obtained with a finite-range two-body pseudopotential complemented with zero-range spin-orbit and density-dependent terms. After discussing the penalty function used to adjust parameters, we discuss predictions for binding energies of spherical nuclei calculated at the mean-field level, and we compare them with those obtained using the standard Gogny D1S finite-range effective interaction.

A new class of pseudopotentials for nuclear structure were introduced several years ago [1, 2, 3]

These pseudopotentials allow for a consistent formulation of the low-energy energy-densityfunctional (EDF) approach in terms of effective theory. This can be done by considering a zero-range effective interaction with derivative terms up to a given order p = 2n, hereafter denoted NnLO [4], and replacing the contact Dirac delta function by a regulator, e−
