We report muon spin rotation/relaxation ({mu}SR) measurements of the heavy fermion superconductor UPt{sub 3} in external fields {ital H}{sub ext}{parallel}{ital {cflx c}}. We find that the muon Knight shift is unchanged in the superconducting state, consistent with odd-parity pairing (such as {ital p} wave). The transverse field relaxation is observed to be strongly field dependent, decreasing with increasing field. Below {ital T}{sub {ital c}} the increase is barely detectable in an applied field of 4 kG{parallel}{ital {cflx c}}. On the basis of the high field measurements, we estimate the low temperature penetration depth to be {lambda}({ital T}{r arrow}0){ge} (R18)11 000 A.
