“…For the reaction 2~176 a much larger part of the l = 0 strength is located in the second 1/2 + state. The theory reproduces this effect, although the calculated value, 38% of the ground-state transition strength, is larger than the observed value of 18_+2%, see [3].…”

Spectra, magnetic dipole moments and spectroscopic factors of a number of A = 205-209 nuclei as well as M1 transitions in 2~ are investigated in terms of large-scale shellmodel calculations which include lp-1 h excitations and for some nuclei 2p-2 h excitations. The calculated spectra agree well with the data. The calculated g-factors are in fair agreement with the data in most cases. The predicted strength for M1 transitions to low-lying states in 2~ is less than that obtained from previous calculations. Spectroscopic factors for l= 0 proton pick-up from 2~ and 2~ agree very well with recent experimental data from (e, e' p) reactions.

Gogny force with a finite-range density dependence

et al. 2015

View full text Add to dashboard Cite

In the present work, we have investigated an extension of the effective nucleon-nucleon Gogny interaction in which the zero-range density-dependent term has been replaced with a finite-range term. The parameters have been adjusted on both nuclear-matter properties and a few observables of stable nuclei. The traditional and unified fitting procedure of the Gogny force used in Bruyères-le-Châtel ensures common basic properties between the extended analytical form of the Gogny interaction, called D2, and the original one. In particular, symmetric infinite nuclear-matter and neutron-matter properties as well as pairing correlations have been investigated. A few static properties obtained in finite nuclei using the Hartree-Fock-Bogoliubov approach and the D2 parametrization of the Gogny interaction are analyzed and compared to the results obtained with D1-type parametrizations and experiment when it is possible. The D2 parametrization makes it possible to reproduce nuclear structure properties with improved accuracy.

“…Some results for the nucleon momentum distribution n (k) extracted from the experimental data now appear in the region of light nuclei [2,3]. Attempts to obtain experimental data for the occupation numbers N v have been made for singleparticle states near the Fermi level in lead isotopes and some nuclei in the rear-earth region [7,8] as well as in the region of the 4~ nucleus [5]. The extracted data for N v are obtained in a model-dependent way [11]o Therefore, experimental data for occupation probabilities in nuclei extracted in a consistent model-independent way are extremely necessary and theoretical predictions in this respect are highly desirable~ For example, the parametrization of the spectroscopic strength spreading used in the (e, e' p) experimental data analyses [5] is highly modeldependent.…”

Abstract. Single-particle occupation probabilities and the depletion of the nuclear Fermi sea (caused by the shortrange nucleon-nucleon correlations) as well as momentum distributions in closed s-d shell nuclei are calculated within the Jastrow correlation method in its low-order approximation. The theoretical results for the occupation probabilities are discussed in relation to experimental data from (e, e' p) reactions and to other theoretical estimates.
