An experiment is proposed to search concurrently for {nu}{sub {mu}} {yields} {nu}{sub e} and {bar {nu}}{sub {mu}} {yields} {bar {nu}{sub e} oscillations with high sensitivity at LAMPF. The detector consists of a tank with 200 tons of dilute liquid scintillator with 850 10-in. photomultiplier tubes mounted on the inside tank covering 28% of the surface. Both Cerenkov light and scintillation light will be detected. The tank will reside inside the existing E645 veto shield and the experiment will make use of the present A6 beam-stop neutrino source. After two years of data collection, 90% confidence level limits on {bar {nu}{sub mu}}({nu}{sub {mu}}) {yields} {bar {nu}}{sub e}({nu}{sub e}) mixing strengths of 2.7(2.7) {times} 10{sup {minus}4} can be obtained for all {Delta}m{sup 2} > 1 eV{sup 2}. Similarly, for maximal mixing the 90% C.L. limits on {Delta}m{sup 2} are 1.7(4.0) {times} 10{sup {minus}2}. This experiment will, therefore, provide the world's best terrestrial limits on {nu}{sub {mu}} {yields} {nu}{sub e}} oscillations. Other physics to be obtained includes measurements of the charged current reactions {nu}{sub e}C {yields} e{sup {minus}}N and {nu}{sub {mu}}C {yields} {mu}{sup {minus}}N, of the inelastic neutral current reaction {nu}C {yields} {nu}C* (15.11- MeV {gamma}), and a search for the rare decays {pi}{sup 0} {yields} {nu}{bar {nu}} and {eta} {yields} {nu}{bar {nu}}.
