Rotational structures in Ta174 and ''identical bands'' in the normal deformation regime
Ta174 has been studied through the Tm169(9Be,4n) fusion-evaporation reaction in the energy range E(9Be)=40-65 MeV. γ- and x-ray in-beam and activity singles spectra, γ-γ-t coincidences, and angular-distribution measurements were performed. Four rotational structures have been found and interpreted o...

| Sumario: | Ta174 has been studied through the Tm169(9Be,4n) fusion-evaporation reaction in the energy range E(9Be)=40-65 MeV. γ- and x-ray in-beam and activity singles spectra, γ-γ-t coincidences, and angular-distribution measurements were performed. Four rotational structures have been found and interpreted on the basis of coupling systematics. Mixing ratio signs have been calculated using a semiclassical method and compared with the signs of the angular-distribution coefficients, in order to consolidate configuration assignments. ''Identical bands,'' i.e., bands with similar transition energies, have been found in neighboring odd and doubly-odd Ta171-174. This similarity is interpreted here as due to fortuitous compensations between different transverse and collective angular momenta and moments of inertia. © 1992 The American Physical Society. |
