The authors have been studying a {gamma}-ray detector which uses a lead iodide PbI{sub 2} crystal. The detector was fabricated from a PbI{sub 2} crystal grown by 10-pass zone traveling molten zone (TMZ) method. The {mu}{tau} product of this crystal is estimated to be about 1 {times} 10{sup {minus}6} cm{sup 2}/V for electrons and about 6 {times} 10{sup {minus}7} cm{sup 2}/V for holes. The resistivity of the PbI{sub 2} crystal is estimated to be about 10{sup 12} {Omega}cm. FWHM energy resolution of the detector for a photoelectric peak for the 59.5 keV {gamma}-rays is found to be about 5 keV.
