摘要：

Gyromagnetic ratios were measured in the 1/2(+)[411] ground-state band of Tm-169 by the transient field technique in such a manner that the extracted g-factors are independent of assumptions concerning the strength and velocity dependence of the transient field. Precise gamma-ray branching intensities and multipolarity mixing ratios were determined from measured particle-gamma-ray angular correlations. The electromagnetic properties of the low-lying natural parity states in Tm-169 are compared with particle-rotor calculations based on the Woods-Saxon potential and the implications of the measured magnetic moments for the calibration of the transient field strength are discussed.
