Abstract

Two γ-rays of 129.2 and 288.4 keV observed in the β-decay of 55 ms 100Rb are interpreted as representing the two lowest transitions in the 100Sr ground-state rotational band. The energy ratio of the two levels, 3.23, approaches the value for a rigid rotator. The half-life of the 2+ state is 5.15 ± 0.20 ns corresponding to a deformation parameter ϵ of 0.29. The theoretical implications of these results are discussed on the basis of a Nilsson-Strutinsky calculation.
