Objective
Neutrinoless double beta decay is expected to probe physics beyond the standard model. The most important observables are a Majorana neutrino mass, right-handed currents in weak interactions, the lepton number conservation, a Majoron existence. The NEMO collaboration has started to build a new tracking detector NEMO-3 designed to measure a double beta decay of different isotopes with masses up to 10 kg. This detector will be capable to reach sensitivity of 0.1 - 0.3 eV for Majorana neutrino mass, 10**(-5) - 10**(-6) for Majoron-Majorana neutrino coupling constant, to study two neutrino double beta decay in detail with high accuracy. Ultra low-backround targets made from materials enriched with 100Mo, 82Se, 116Cd, 130Te, 96Zr and 76Ge are planned to use in the NEMO-3 detector.
The detector will be totally assembled in July 1998 and will be in operation from September 1998.
NEMO collaboration will continue theoretical investigations of double beta decay problem with the aim to improve the quality of nuclear matrix element calculations and, as a result, to produce more correct limits( or values!) on neutrino mass, right handed current parameters, Majoron-Majorana neutrino coupling constant etc. It is planned to produce new results for many nuclei (100Mo, 116Cd, 92Mo, 106Cd, 96Zr, 82Se, 130Te, 136Xe) using different theoretical schemes(pn-QRPA, RQRPA, shell model).
Description of the spectrometer, as well as physical results will be published in scientific journals and presented at the International Conferences.
