The NEMO-3 experiment performed precise measurement of the double beta decay and searched for the neutrino-less double beta decay on seven isotopes, among which 100 Mo and 82 Se were the dominant ones.The detector, installed in the Laboratoire Souterrain de Modane, took data for 8 years before being decommissioned in 2011.The key feature of NEMO-3 was its unique capability to fully reconstruct the kinematics of the events, which allowed to reduce the backgrounds and to discriminate among different mechanisms beyon…
