The optical output of the bright Type I supernova 1972e is examined in detail to test the fluorescence theory of supernova light. The output is divided into a rather red quasi-Planckian continuum with its accompanying emission and absorption lines, which is due to the expanding gas shell ejected in the explosion, and the wide fluorescent emission lines together with a weak blue two-photon continuum. The predicted 10124-A line of He II is found in the correct position with roughly the intensity given by the simplest fluorescent model, and the form of the prolonged light-curve tail as well as the two identifiable lines of He II are shown to support the fluorescent model. The presence is noted of other, unidentified strong lines of fluorescent origin. It is concluded that the total radiative output of a Type I supernova is at least tens of times greater than all that observed in the IR and visible bands.
