The ground-state deformation of98Sr

Zeitschrift für Physik A Atomic Nuclei

Abstract

The half-life of the first excited state (2 +1 ) of98Sr has been determined through the measurement of delayed γ-γ coincidences at the fission product separator OSTIS to t1/2=2.74(12) ns. This value is smaller than those obtained earlier from β− — conversion electron delayed coincidences and it indicates a stronger collectivity of the 2 +1 →0 +1 transition in98Sr [B(E2)=98 (3) spu] than in100Sr [B(E2)=79(3) spu] which is normally assumed to be the better rotor.
