The Gamow-Teller β decay of Cr46 to the N=Z odd-odd nucleus V46 has been observed for the first time. Cr46 was produced by the fragmentation of a Cr50 primary beam at 80 MeV/nucleon. By means of β-γ coincidence measurements, a γ-ray peak at 993 keV corresponding to the decay of the 11+ state in V46 was observed. The branching ratio of the Gamow-Teller decay to this state was found to be bGT=0.216±0.050. The half-life of Cr46 was measured to be T1/2=240±140 ms. The transition strength was determined to be B(GT)=0.64±0.20. This result was compared with theoretical values calculated with the shell model and the phenomenological quasideuteron model.
