Search of neutrino-less double beta decay of Neodymium 150 in the NEMO3 experiment

For the NEMO3 CollaborationThe NEMO3 experiment has taken data from 2003 to 2011 in the Modane Underground Laboratory (France). Its goal is the search for the neutrino-less double β decay in order to prove that the neutrino is a Ma jorana particle. The tracko-calo technology allows this detector to well separate between background and signal contributions. No evidence of neutrino-less has yet been shown. The double β decay with neutrinos emission, allowed by the Standard Model, has been measured for 7 different isotopes and I will focus especially on the analysis of the Neodymium 150
