SrI_2, a Novel Scintillator Crystal for Nuclear Isotope Identifiers

摘要

The growth and scintillating properties of undoped and Eu~(2+) doped Strontium Iodide indicate excellent potential for gamma ray spectroscopy. Energy resolution at 662 keV was found to be as good as 2.7% at 662 keV. The effect of purification by zone refining was also studied and crystal growth of SrI_2 by the Bridgman technique was found to be less subject to cracking compared to the growth of lanthanum halide scintillators.
