Induced conductivity in CdS crystals produced by electron bombardment (cathodoconductivity) and the associated x‐ray production have been studied employing electrons in the 30‐ to 60‐kev range. The conductivity induced solely by these x‐rays has been studied. Using classical x‐ray theory, the production and absorption of x‐rays in the experimental crystals have been calculated. Some confirmatory data are presented. From calculated excitation rates and observed conductivities the x‐rays produced by impinging electrons are shown to be sufficient to explain the effects observed in cathodoconductivity, and may be significant in cathodoluminescence.
