Decays of 88Kr and 88Rb

The γ rays following the β decays of 88Kr and 88Rb have been studied, using both large volume Ge(Li) detectors for singles and coincidence measurements and anti-Compton spectrometry for singles measurements. Level schemes for 88Rb and 88Sr were constructed from the data and 74 of 81 γ rays observed in the decay of 88Kr were placed in the 88Rb level scheme with 23 excited states. For the decay of 88Rb, all of the observed 27 γ rays have been placed in the (well known) level structure of 88Sr. Spin and parity assignments have been deduced from β-decay logft values and γ-ray transition patterns. Possible shell model interpretations are presented for the level schemes
