Nuclear orientation study of the decay of148Eu

Abstract
The authors have measured the angular distributions of 43 gamma rays in 148Sm following the decay of 148Eu polarised at low temperatures in an iron host. Multipole mixing ratios are deduced for 39 transitions; three X(E0/E2) values are also decided. They calculate these quantities, as well as excitation energies and B(E2) values, using the IBA-1 model. The mixing ratios are seen to be a sensitive probe of the wavefunctions.
