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

Abstract

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