Abstract
The nuclides and have been produced by spallation reactions on vanadium targets at MeV. The subsequent decays to and states have been studied. An intensity of 98.6 ± 0.6% was measured for the transition to the 1.94 MeV state in . A decay scheme involving 13 branches has been established for , and the corresponding values have been deduced. Eleven states are reported for the first time in the decay scheme of at 1.42, 1.47, 1.72, 2.52, 2.57, 2.75, 3.31, 3.99, 4.04, 4.36, and 4.57 MeV. From the lifetime, ns, deduced from delayed coincidences, the angular momentum of the 1081 keV level has been established as on the basis of the transition strength of its decay. A survey on the transition in odd K nuclei is presented and the observed hindrance factors are discussed.
