Abstract

Low and medium spin collective structures in ¹⁵⁸Er have been studied using the ¹⁵⁰Sm(¹²C,4nγγ) fusion-evaporation reaction at a beam energy of E_lab= 65 MeV. A band built on the 0₂⁺excitation has been established and extended to J^π= 18⁺from the analysis of γ-γ coincidence relationships, intensity arguments and DCO ratios. The 0 ₂⁺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.
