Abstract
We discuss possible deviations from QED produced by a virtual excited spin- 3/2 lepton in the reaction e(+)e(-) --> 2 gamma. Data recorded by the OPAL Collaboration at a c.m. energy root s = 183 GeV are used to establish bound s on the nonstandard-lepton mass and coupling strengths. [S0556-2821(99)015 19-2].
