Abstract
Scintillation properties of calcium molybdate are investigated. Emission spectrum is broad with a maximum at 520 nm, at room temperature light yield is 400 photoelectrons/MeV, decay time is 17 μs, at cooling light yield and decay time increase. Prospects of optimization of this scintillator are discussed. Feasibility of the material for the search of neutrinoless double beta decay of 100Mo is analyzed. Half life limit of T12/ = 1 · 1025 years (68% CL) seems feasible with CaMoO4 scintillator, containing 10 kg of 100Mo after 5 year of measurements. The problem of background due to two neutrino double beta decay of 48Ca is considered. Request for new scintillators for double beta decay search is formulated.
