TLDR
In this paper, the Hartree-Fock potential with the Gogny D1 effective interaction or the Perey-Buck potential is employed to calculate the polarization and correlation contributions to the real part via the dispersion relation.Citations

Single-Particle Motion in Nuclei
C. Mahaux,R. Sartor +1 more
TL;DR: In this paper, the authors consider a unified treatment in which the shell model potential is also complex and is the continuation of the optical-model potential, and they enable one to construct the complex shell- model potential by extrapolating the optical model potential from positive toward negative energies.

Chiral approach to nuclear matter: role of two-pion exchange with virtual delta-isobar excitation
TL;DR: In this paper, the effects from two-pion exchange with single and double virtual Δ (1232 ) -isobar excitation were investigated. And the effects of 2π-exchange with virtual Δ-excitation on the nuclear energy density functional were also investigated.

A systematic study of nuclear properties with Skyrme forces
TL;DR: In this article, a systematic study of nuclear properties with Skyrme forces is presented, including nuclear ground state properties with Hartree-Fock (HF) and self-consistent semiclassical approaches.
Journal ArticleDOI
Semiclassical and phase space approaches to dynamic and collisional problems of nuclei
TL;DR: In this article, the semiclassical treatment of the nuclear response function is given in detail, and applications to inelastic electron scattering in the quasi-elastic peak region are presented.

Correlation effects on the level density of a hot nucleus
Rainer W. Hasse,Peter Schuck +1 more
TL;DR: In this paper, the previously introduced model for correlation effects on the level density parameter, a, is generalized to finite temperatures and it is found that the increase of a due to the correlations at zero temperature vanishes within a certain range around T ≈ 4 MeV, in agreement with recent experimental studies.

The Nuclear Many-body Problem
TL;DR: In this paper, the Hartree-Fock method pairing correlations and superfluid nuclei was used to restore broken symmetries in the generator coordinate method of the generator-coordinate method.

A non-local potential model for the scattering of neutrons by nuclei
F.G. Perey,B. Buck +1 more
TL;DR: In this article, an energy independent non-local optical potential for the elastic scattering of neutrons from nuclei is proposed and the wave-equation solved numerically in its full integro-differential form.
Journal ArticleDOI
Damping of nuclear excitations
TL;DR: In this paper, the authors review the theory and the empirical evidence of damping of simple nuclear excitations, including the particle states and vibrational states, and compare theory and empirical evidence.

Mean free path in a nucleus
John W. Negele,Koichi Yazaki +1 more
TL;DR: In this paper, proper treatment of the nonlocality of the nuclear optical potential resolved much of the apparent discrepancy between previous theoretical calculations and empirical values of the nucleon mean free path.
