Limits on probability of 2b-decays of 116Cd to excited levels of 116Sn, on 2b-decays with Majorons emission, and for 2b-processes in 106Cd, 108Cd, 114Cd nuclei were established (most of them are the best in the world and some are obtained at first time). Limit on the neutrino mass (<mn><1.7 еВ), and right-handed currents in weak interactions were obtained. The accuracy of measured T1/2 for double-neutrino mode 2b-decay of 116Cd was improved more than twice, limits on 0n2b-decay of 180W, 186W and 160Gd (Solotvina Underground Laboratory) were measured. In Gran Sasso Underground Laboratory experimental limits on rare processes in 48Ca, a-decay of 142Ce and 2К2n capture in 136Ce were obtained. Bounds on possibility of proton decay by "invisible" channels (neutrino emission, dissapearance etc.) was obtained. Limits on b-decay of 73Ge with electrical charge nonconservation wereobtained. At the first time a-decay 180W was seen and the period of half-life was measured. Limits on decays of nucleon pairs (di-nucleon) in variuos nuclei by "invisible" channels were estimated.
