  The Daejeon16 two-nucleon interaction is employed in many-body approaches
based on the mean-field approximation. The perturbative character of Daejeon16
is verified by comparing results for 16O from the Hartree-Fock (HF)
approximation and from the no-core shell model and by examining the magnitude
of perturbative corrections to the HF energy in light and heavy nuclei. In
order to approximately describe energies and radii across the nuclear chart, a
phenomenological correction in the form of a two-plus-three-nucleon contact
interaction is introduced. With fitted parameters we achieve a very good
description of medium-mass nuclei in terms of energy and size and also in terms
of the centroid energy of the giant monopole resonance and the dipole
polarizability calculated within the random-phase approximation (RPA). Our
results provide further justification for the use of Daejeon16 augmented with
phenomenological corrections as an effective interaction of perturbative
character in a variety of applications.
