We use ..nu../sub ..mu../-deuteron reactions into exclusive multipion final states to determine the extent to which atmospheric ..nu.. interactions can imitate nucleon decay. For decays N..-->..l/sup c/..pi../sup c/..pi../sup c/ (l/sup c/..pi../sup c/..pi../sup c/..pi../sup 0/), neutrinos induce background events at the rate 0.07 +- 0.06 (0.03 +- 0.02) per kiloton year. By requiring a multipion final state to be consistent with a rho, ..omega.., or eta, a fivefold reduction of the background is obtained. Thus present-generation experiments are capable of searching for such decays at a lifetime level corresponding to many kiloton years of detector exposure.
