AbstraktAbstract
Investigations of double beta decay processes to excited states of daughter nuclei were performed at the Modane underground laboratory (LSM, France, 4800 m w.e.) using the high sensitivity spectrometer OBELIX, which is a common activity of JINR Dubna, IEAP CTU in Prague and LSM. The spectrometer is based on the HPGe detector with the sensitive volume of 600 cm3 and relative efficiency of 160%. Investigation of resonant neutrino-less double electron capture of 106Cd was performed with 23.2 g of 106Cd (enrichment of 99.57%) during 17 days. The experiment with natural Ni (21.7 kg of mass) was also carried out during 47 days. The preliminary experimental limits for 0nEC/EC resonant decay to the excited states of 106Pd and different modes of beta beta decay 58Ni are presented.
