Abstract

The gyromagnetic ratios of the lowest excited 32 and 52 states in 107, 109Ag were simultaneously measured relative to that of the 21+ level in 108Pd. The thin-foil, perturbed γ-ray angular distribution technique was employed utilizing the transient hyperfine magnetic field present at the nuclei of these ions as they swiftly recoiled through a thin magnetized Co foil. The states of interest were Coulomb-excited using beams of 100 MeV 32S ions. The present measurements yielded g(32; 107Ag) = +0.63 ± 0.09, g(52; 107Ag) = + 0.37±0.06, g(32; 109Ag) = +0.77 ± 0.10, and g(52; 109Ag) = +0.36 ± 0.05. These findings are compared with weak-coupling and other appropriate model calculations.
