Description

Wave functions obtained in previous shell-model calculations for states of nuclei with masses A = 10-15 are used to calculate log ft values and spectroscopic factors. These wave functions, which were based on a modified surface delta two-body interaction, comprise the following active shell-modell spaces: the 1psub(3/2) and 1psub(1/2) orbitals for mass 10-14 nuclei and restricted combinations of the 1psub(1/2), 2ssub(1/2), 1dsub(5/2) and 1dsub(3/2) orbitals for mass 15 nuclei, leading to four different calculations in the latter case. The calculated results support evidence that the modified surface delta interaction is a valid approximation to the effective interaction in light nuclei. (orig.)

Abstract (German)

Unter Verwendung von Schalenmodell-Wellfunktionen fuer Zustaende von Kernen der Massen A = 10-15 werden log ft-Werte und spektroskopische Faktoren berechnet. Diese Wellenfunktionen basieren auf einer modifizierten deltafoermigen Oberflaechen-Zweikoerperwechselwirkung und enthalten folgende aktive Schalenmodellraeume: 1psub(3/2) und 1psub(1/2)-Orbitale fuer Kerne der Massenzahlen 10-14 und beschraenkte Kombinationen der 1psub(1/2), 2ssub(1/2), 1dsub(5/2) und 1dsub(3/2) Orbitale fuer A = 15 Kerne, was im letzten Fall zu vier verschiedenen Rechnungen fuehrt. Die berechneten Ergebnisse zeigen, dass die modifizierte Oberflaechendeltawechselwirkung eine brauchbare Naeherung der effektiven Wechselwirkung in leichten Kernen darstellt. (orig.)
