We present the results of a search in p (p) over bar collisions at roots=1.8 TeV for anomalous production of events containing a photon and a lepton (e or mu ), both with large transverse energy, using 86 pb (-1) of data collected with the Collider Detector at Fermilab during the 1994-1995 collider run at the Fermilab Tevatron. The presence of large missing transverse energy (is not an element of(T)), additional photons, or additional leptons in these events is also analyzed. The results are consistent with standard model expectations, with the possible exception of photon-lepton events with large is not an element of(T), for which the observed total is 16 events and the expected mean total is 7.6+/-0.7 events.
