Description

Low and medium spin collective structures in 158Er have been studied using the 150Sm(12C,4nγγ) fusion-evaporation reaction at a beam energy of Elab= 65 MeV. A band built on the 02+ excitation has been established and extended to Jπ= 18+ from the analysis of γ-γ coincidence relationships, intensity arguments and DCO ratios. The 02+ band in 158Er presents a similar trend to the 02+ bands in the lighter N = 90 isotones but lies about 125 keV higher. This systematic trend supports a similar configuration for the 02+ bands in the N = 90 isotones. (authors)
