Abstract

Transient-field precessions were measured for levels in ¹⁹⁷Au and ^182,184,186W as their ions simultaneously traversed polarized Gd hosts. Gyromagnetic ratios were inferred for the positiveparity levels between, and including, the lowest 5 2⁺ and 11 2⁺ states in ¹⁹⁷Au. Lifetimes of several levels were determined using the Doppler-broadened lineshape technique, and multipole mixing ratios of a number of transitions were deduced from measured particle-γ-ray angular correlations. The measured static and dynamic electromagnetic moments are compared with the predictions of the weak-coupling core-excitation model and with those of the interacting boson-fermion model (IBFM), including its Spin(6) supersymmetry limit.
