Description

Binding energies excitation energies ans spectroscopic factors have been calculated for 57-67Ni and 58-68Cu in an unrestricted (2p3/2, 1f5/2, 2p1/2) shell-mode space. The effective two-body matrix elements are obtained from the modified surface delta ineraction (MSDI) and from a least-squares fit to experimental binding and excitation energies (ASDI). The average deviation between about 100 experimental and calculated energies is 0.14 MeV for MSDI and 0.08 Mev for ASDI. Excitation energies of high-spin states are given also. Spectroscopic factors have been calculated for all single-nucleon transfer reactions on stable Ni or Cu targets leading to Ni or Cu isotopes. (orig./BJ)

Abstract (German)

Fuer 57-67Ni und 58-68Cu wurden in einem unbeschraenkten (2p3/2, 1f5/2, 2p1/2)-Schalenmodellraum Bindungsenergien, Anregungsenergien und spektroskopische Faktoren berechnet. Die effektiven Zweikoerper-Matrixelemente erhaelt man aus der modfizierten Oberflaechen-Deltawechselwirkung (MSDI) und aus einer Anpassung mittels der Methode der kleinsten Quadrate an experimentelle Bindungs- und Anregungsenergien (ASDI). Die mittlere Abweichung zwischen etwa 100 experimentellen und berechneten Energien betraegt 0,14 MeV fuer MSDI und 0,08 MeV fuer ASDI. Es werden aus Anregungsenergien fuer Zustaende mit hohem Spin geliefert. Spektroskopische Faktoren wurden fuer alle Einnukleon-Uebertragungsreaktionen an stabilen Ni- oder Cu-Targets, die zu Ni- oder Cu-Isotopen fuehren berechnet. (orig./BJ)
