Abstract
WE have examined spectrographically the light emitted by thin films bombarded by α-particles1. The films were built up by evaporation on quartz slides to a thickness small compared with the range of the α-particles. The slides were mounted in front of the slit of a Hilger f/4 quartz spectrograph and exposed to a 25-mC. polonium source. Representative spectra, photographed on Eastman Kodak type II-0 spectroscopie plates, are shown in the accompanying photograph.
