We present the results of a search for neutrino oscillations at the Brookhaven National Laboratory. The experiment searched for the appearance of {nu}{sub {ital e}} ({bar {nu}}{sub {ital e}}), 1 km from the source of a wide-band {nu}{sub {mu}} ({bar {nu}}{sub {mu}}) beam. The experiment used a total of 3{times}10{sup 19} protons on target from the Alternating Gradient Synchrotron. The data collecting was split evenly between positive and negative horn polarities, corresponding to neutrino and antineutrino beams. No excess of {nu}{sub {ital e}} or {bar {nu}}{sub {ital e}} over the expected backgorund was detected. The 90%-confidence-level limits obtained are {Delta}{ital m}{sup 2}{le}0.075 eV{sup 2} for maximal mixing, and sin{sup 2}2{theta}{le}0.003 for large {Delta}{ital m}{sup 2}.
