Collectivity of Po-196 at low spin
Résumé
Absolute electromagnetic transition probabilities in Po-196 have been measured using the recoil distance Doppler-shift technique. The lifetimes of the three lowest yrast states in Po-196 were extracted from singles gamma-ray spectra by using the recoil-decay tagging method. In addition, configuration mixing calculations of angular momentum projected mean-field states have been carried out for Po-196. The present study sheds light on the onset of collectivity and mixing of competing structures in neutron-deficient Po nuclei.
