Relative Importance of Relativistic Induced Interactions in the beta Decay of sup 170 Tm

摘要

The log ft-values, the spectrum shape functions, and the beta-gamma angular correlation coefficients of the sup 170 Tm beta decay are computed in the framework of relativistic form factor formalism using asymmetric rotor model wavefunctions. Main vector and axial vector hadron currents being strongly hindered, the relative importance of induced interaction matrix elements is accurately estimated. Good agreement with experiment is obtained for the beta decay observables when the main induced interaction terms were taken into account. The contribution of the pseudoscalar term was found insignificant. (Atomindex citation 15:066145)
