CONDUCTIVITY CHANGES PRODUCED IN ICE BY OPTICAL IRRADIATION .8 TO 2.7.
A series of experiments attempt to produce orientational defects and ions by optical injection. The basic experiment was one on transient photo-conduction produced by an intense light pulse. The effects of intensity and wavelength of the incident light, temperature of the sample and area of illumina...
