| Abstract: | The gyromagnetic ratios of the 21+, 41+, 61+, 22+, and 23+ states in 150Sm and the 21+, 41+, 61+, 81+, 101+, 22+, and 23+ levels in 152Sm have been measured using the transient field perturbed γ-ray angular correlation technique. States of interest were populated by multiple Coulomb excitation using 150- and 220-MeV 58Ni beams. The present results display no significant deviation from constancy of the g-factors of all levels investigated in either isotope separately or of corresponding states in 150,152Sm. These findings are compared with available prior measurements and assessed in terms of applicable theoretical model calculations. |
