Abstract
The Gamow-Teller decay of to the odd-odd nucleus has been observed for the first time. was produced by the fragmentation of a primary beam at 80 MeV/nucleon. By means of coincidence measurements, a γ-ray peak at 993 keV corresponding to the decay of the state in was observed. The branching ratio of the Gamow-Teller decay to this state was found to be . The half-life of was measured to be ms. The transition strength was determined to be . This result was compared with theoretical values calculated with the shell model and the phenomenological quasideuteron model.
