1 PublicationLow-energy M1 strength in deformed nuclei
Schwengner, R.
Abstract
Large-scale shell-model calculations were performed for 56Fe, 60Fe, 64Fe and 68Fe. The collective properties of yrast states are reproduced in the used model space.
The low-energy enhancement of M1 strength decreases with increasing deformation, while a bump around E = 3 MeV develops, which can be related with the scissors mode. The strength around E = 3 MeV includes transitions from 1+ states to the ground state as well as to excited 0+ states and contributions from other spins.
The average M1 strength is rather independent of the excitation energy for Ei > 5 MeV. This validates the Brink-Axel hypothesis in this energy region.
Keywords: Gamma-ray strength functions; M1 transitions; shell-model calculations
