Abstract
The mechanism of charge carrier generation by X-rays in anthracene cry stals has been studied. We conclude that charge carrier pairs are gene rated by electrons due to the scattering of X-rays and the separation mechanism is in disagreement with the Onsager model. Recombination of charge carriers determines the slope of the photocurrent-electric fiel d characteristics. The experimental current-electric field characteris tics have been described theoretically and the role of photoinjection of charge carriers by X-rays from metallic electrodes has been establi shed.
