Lifetime measurements in70Se and72Se

  • Published:
Zeitschrift für Physik A Atomic Nuclei

Abstract

Mean lives and limits of lifetimes have been determined for some ten mostly yrast states in70Se, by means of the recoil distance Doppler shift technique. The states were excited in the reaction40Ca(36Ar,α2p) at 115 MeV resp. the reaction58Ni(14N,pn) at 39 MeV beam energy. The systematic decrease ofB(E2) values along the the ground band transitions indicates a band crossing consistent with theγ-ray energies. Effects of continuum feeding times in both reactions are being discussed. The lifetimes of the lowest three yrast transitions in72Se have been remeasured by means of the reactions40Ca(36Ar,4p) and60Ni(14N,pn).
