Attempts to reproduce as closely as possible the observation of Professor Schwartz that electrons, after interacting with an intense laser beam in a thin transparent film, gave off light when they struck a non-fluorescent screen. An electron beam of approximately 40,000 electron-volts and a pulsed laser beam of 40 watts peak power were made to intersect at right angles in 1,000 Angstrom thin transparent films of amorphous quartz SiO2, polycrystalline sapphire Al203, and monocrystalline mica. Light given off when transmitted electron beam struck a non-fluorescent alumina target was searched for with a sensitive photomultiplier capable of detecting single photons. No light that could be attributed to modulation of the electrons was detected. Further experimental work was devoted to modulating an electron beam with light and electronic detection of the modulation. This approach was an attempt to separate the original experiment in two parts The results of this experiment was also negative. Author
