摘要：

A search for nu(mu) - nu(e) oscillations has been conducted with the LSND apparatus using v(mu) from pi(+) decay in flight. Two analyses observe a total of 40 beam-on high-energy (60-200 MeV) electron events consistent with the nu(e) C --> e(-) X inclusive reaction. This number is significantly above the 21.9 +/- 2.1 events expected from the nu(e) contamination in the beam and the beam-off background. If interpreted as an oscillation signal, the observed oscillation probability of (2.6 +/- 1.0 +/- 0.5) x 10(-3) is consistent with the previously reported <(nu)over bar>(mu) --> <(nu)over bar>(e) oscillation evidence from LSND.
