First results from the $\nu_{\mu} \to \nu_{e}$ oscillations search in the NOMAD experiment

The NOMAD experiment has been optimized to detect primary electrons with good efficiency. lie charged current interactions can be analysed to search for a 11µ -; lie signal: no evidence for such a signal is observed in the NOMAD data collected during 1995 run. Comparing the ratio ve /llµ of observed v, and llµ charged current interactions to expectations shows no evidence for oscillations. A preliminary limit of sin2 2(J < 1.8 x io-3 can be set for high Ll.m2 .
