Gyromagnetic ratios of excited states in ¹⁵⁰Sm and ¹⁵²Sm

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.
