Abstract
An event consistent with the signature expected for the rare kaon decay K+ --> pi+ nu anti-nu has been observed. In the pion momentum region examined, 211<P<230 MeV/c, the backgrounds are estimated to contribute 0.08 +/- 0.03 events. If the event is due to K+ --> pi+ nu anti-nu, the branching ratio is (4.2 +9.7/-3.5) x E-10.
