摘要：

The paper presents a theoretical model to describe the charge collection process for HgI2 gamma detectors. The standard deviations of full energy peak distributions are shown as a function of mean drift lengths of electrons and holes. Calculated spectra shape changes versus variation in the internal detector electrical field distribution are studied. Simulated spectra are compared with experimental data. The model assumptions and results are discussed.
