Rotational structures in Ta174 and ''identical bands'' in the normal deformation regime

Mostrar todas las versiones(2)

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...
