In the Solotvina Underground Laboratory prototype of low-background spectometer for radioactive contamination of scintillastors was created. More precisely half-life of 180W by alpha-decay was determined: T1/2=1,1+0,8 0,3·1018 y. Simulation of solar neutrino in the detector based on liquid Хе was done. Limits on proton lifetime were determined t> 3.5·1028 y. Pauli principle for nuleons was checked. Limits on decays nn and pp were adjusted. New limits on electric charge nonconserving (CNC) decay of electron we received. Electron nonstability was searched. Alpha-beta ratio, spectrometric properties, possibilities of pulse shape discrimination and radioactive purity of CeF3, which are important for WIMP detection due to spin-dependant interaction with 19F, were investigated.
