Abstract

A search for double beta decay of 64,70Zn, 180,186W was carried out by using low background ZnWO4 crystal scintillators while a CeCl3 scintillation detector was applied to investigate 2beta processes in 136,138,142Ce. A search for 2beta decay of 96,104Ru, 156,158Dy, 190,198Pt and study of 2ν2beta decay of 100Mo to the first excited 0+ level of 100Ru were realized by ultra‐low background HPGe gamma spectrometry. Moreover CdWO4 crystal scintillators from enriched 106Cd and 116Cd isotopes were developed to search for 2beta decay of 106Cd and 116Cd. Finally experiments aimed to investigate 96,104Ru and 116Cd are in progress and a new phase of the experiment to search for 2beta processes in 106Cd is in preparation.
