Abstract

We report on a search for the rare decay

{\bar{B}}^{0} \to D^{* 0} γ

, which in the standard model is dominated by

W

-exchange. The analysis is based on a data sample comprising

87.8 \times 10^{6}

B \bar{B}

pairs collected with the BABAR detector at the PEP-II asymmetric-energy

B

Factory at SLAC. No significant signal is observed, and an upper limit on the branching fraction of

2.5 \times 10^{- 5}

at the 90% confidence level is obtained.
