Abstract
Delayed rays following the decay of two new proton-rich Kr isotopes have been observed. These isotopes were produced by the bombardment of with ions, and were separated from contaminant activities by a gas-transfer system. decays with a half-life of 17.4 ± 0.4 sec to states in , with the subsequent emission of six rays. decays with a half-life of 25.9±0.6 sec to states in , and emits eight rays. Identification of the Kr isotopes was based both on the buildup of their daughters, and on relative intensities of decay rays observed at two different bombarding energies. Decay schemes are presented, and the astrophysical significance of is discussed.
