We have computed, in detail, the energy and angular distribution of the leptons (l) produced by the decay of winos (W-tilde) via the reaction e/sup +/e/sup -/ ..-->.. W-tilde/sup +/ + W-tilde/sup -/ ..-->.. l/sup +/nu..gamma..-tilde + l/sup -/anti nu..gamma..-tilde within the framework of a supergravity electroweak model. We have also computed the backgrounds to this reaction from the production and subsequent decays of tau/sup +/tau/sup -/ pairs or pairs of new sequential heavy leptons. We conclude that it is possible to distinguish the wino from an ordinary heavy lepton and, moreover, that winos lighter than the W-boson would be clearly identifiable at LEP energies. 22 refs., 3 figs.
