Abstract
Using a neutrino beam in which a v(tau) component was identified for the fi rst time, the vr magnetic moment was measured based on a search for an anom alous increase in the number of neutrino-electron interactions. One such ev ent was observed when 2.3 were expected from background processes, giving a n upper 90% confidence limit on mu (v tau) of 3.9 x 10(-7) mu (B) . (C) 200 1 Published by Elsevier Science B.V.
