| Sumario: | The structure of the γ-vibrational band-heads in the rare-earth region is examined in relation to the different types of interaction matrix element that appear within the framework of the quasi-particle random phase approximation. The systematic trends of the force coupling constants, the B(E2) transition rates and the quasi-particle numbers in the correlated ground state of the nuclei are analysed in particular situations in which the interaction between quasiparticles contains either particle-particle or particle-hole terms, or both. The effects of schematic and non-schematic model calculations are discussed. © 1973. |
