Abstract
Development of low background CdZnTe detectors is in progress to study neut rino-less double beta decay. The mu tau product (mobility times lifetime) f or holes was measured in a set of CdZnTe detectors at various temperatures between +22 degrees C and -40 degrees C in order to investigate charge coll ection efficiencies for holes. The sensitivity of CdZnTe detectors to neutr ino-less beta(+)EC decays of Zn-64 (Zn-64 + EC --> Ni-64 + beta(+)) is esti mated from these data. (C) 1999 Elsevier Science B.V. All rights reserved.
