摘要：

One manifestation of polarization commonly observed in mercuric iodide gamma-ray spectrometers is as a gradual improvement in spectral response after application of bias voltage. Gamma-ray spectral data are presented which demonstrate this phenomenon. Data is also presented which suggest that the polarization is related to a gain mechanism, most likely Auger recombination. This model is used to explain changes in hole lifetimes and the effects of light exposure on gamma-ray response.
