A review is presented of the development and current status of nuclear shell-model calculations, in which the two-body effective interaction between valence nucleons is derived from the free nucleon_nucleon potential. The significant progress made in this field within the last decade is emphasized, in particular as regards the so-called Vlow??k approach to the renormalization of the bare nucleon_nucleon interaction. In the last part of the review, we first give a survey of realistic shell-model calculations from early to present days. Then, we report recent results for neutron-rich nuclei near doubly magic 132Sn, and for the whole even-mass N D 82 isotonic chain. These illustrate how shellmodel effective interactions derived from modern nucleon_nucleon potentials are able to provide an accurate description of nuclear structure properties.

Abstract
A review is presented of the development and current status of nuclear shell-model calculations, in which the two-body effective interaction between valence nucleons is derived from the free nucleon_nucleon potential. The significant progress made in this field within the last decade is emphasized, in particular as regards the so-called Vlow??k approach to the renormalization of the bare nucleon_nucleon interaction. In the last part of the review, we first give a survey of realistic shell-model calculations from early to present days. Then, we report recent results for neutron-rich nuclei near doubly magic 132Sn, and for the whole even-mass N D 82 isotonic chain. These illustrate how shellmodel effective interactions derived from modern nucleon_nucleon potentials are able to provide an accurate description of nuclear structure properties.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
