| Research Abstract |
Measurement of neutrino-less double beta decay provides a test for the Majorana nature of neutrinos and gives an absolute scale of the effective neutrino mass. In order to search for neutrino-less double beta decay of^<48> Ca, we constructed CANDLES system by using CaF2 scintillators. We checked the performances of the CANDLES system and started a measurement of neutrino-less double beta decay. The sensitivity of the CANDLES III system is 0. 5eV for neutrino mass.
