Abstract
We have been studying a gamma-ray detector which uses a lead iodide Pb I2 crystal. The detector was fabricated from a PbI2 crystal grown by 1 0-pass zone travelling molten zone (TMZ) method. The mu tau product of this crystal is estimated to be about 1 x 10(-6) cm(2)/V for electron s and about 6 x 10(-7) cm(2)/V for holes. The resistivety of the PbI2 crystal is estimated to be about 10(12) Omega cm. FWHM energy resoluti on of the detector for a photoelectric peak for the 59.5 keV gamma-ray s is found to be about 5 keV.
