Abstract

High spin states in the odd proton nucleus 129La have been investigated using the techniques of in-beam gamma-ray spectroscopy. Nine rotational bands have been observed in 129La, seven for the first time. Various band crossings were observed at rotational frequencies in the range h-omega = 0.28-0.57 MeV. The data are mainly discussed within the framework of the cranked shell model. The rotational bands are assigned quasiparticle configurations originating from pi-h11/2, pi-g7/2, pi(h11/2)2 x pi-g7/2 and pi-h11/2 x nu(h11/2g7/2) states, respectively. Four of the band crossings are thought to be associated with the rotational alignments of the first pair of h11/2 neutrons or protons.
