Abstract

The systematics of excitation energies, single-particle spectroscopic factors and electromagnetic transition rates of levels belonging to the Kπ = 12 bands based on the Nilsson orbits 4 and 14 in the odd-A = 19–31 nuclei have been studied and compared to weak-coupling and particle-rotor model predictions. Both bands are characterized by large decoupling parameters. The E1 transition rates are found to be typically of the order of 10−4 to 10−3 W.u., which is normal for this mass region. The transitions within the 12[101] band are enhanced, stretched E2 transitions. The over-all agreement with the model predictions is good.
