{sup 128,130,132,134}La in the axially symmetric rotor model

Recent experimental data on positive-parity yrast states, based on the {pi}{ital h}{sub 11/2}{direct_product}{nu}{ital h}{sub 11/2} configuration, of odd-odd {sup 128,130,132,134}La are compared in a systematic way with the energies and transition probabilities calculated within the framework of the two quasiparticle, axially symmetric core model. It is found that very good agreement is obtained in {sup 128,130}La assuming prolate deformation. Influence of the neutron Fermi level on the level properties in these two nuclei has also been studied. In the case of {sup 132,134}La, this model seems to indicate that this positive parity yrast band may have an oblate deformation.
