Description

Nuclear system interacting via quadrupole and octupole particle-hole forces is studied by the boson expansion technique. Energy spectra of the negative parity yrast band and the ground state band are calculated and compared with experiment for 100Ru, 112Cd, 150Sm and 150Gd. Experimental B(E1)/B(E2) ratios show strong hindrance for E1 transitions, and are used to deduce the static polarizability of E1 transitions. (orig.)

Abstract (German)

Mit Hilfe der Methode der Bosonen-Entwicklung wird die Wechselwirkung eines Kernsystems ueber Quadrupol- und Oktupol-Teilchen-Loch-Kraefte untersucht. Die Energiespektren der Yrast-Bandes negativer Paritaet und des Grundzustandsbands werden berechnet und mit experimentellen Daten fuer 100Ru, 112Cd, 150Sm und 150Gd verglichen. Die experimentellen B(E1)/B(E2)-Verhaeltnisse zeigen eine starke Unterdrueckung der E1-Uebergaenge und werden zur Ableitung der statischen Polarisierbarkeit der E1-Uebergaenge herangezogen. (orig.)
