Abstract

A radiopure cadmium tungstate scintillator enriched in Cd-106 to 66% ((CdWO4)-Cd-106) operates in coincidence (anticoincidence) with two CdWO4 scintillation counters to search for double-beta processes in Cd-106. After 26033 h of data taking, no effects were observed. The half-life limits on the different channels of Cd-106 double-beta decay were set at the level of T-1/2 similar to 10(20) - 10(22) yr. A new stage of the experiment is running with an improved sensitivity to all the decay channels thanks to reduction of the background and improvement of the energy resolution.
