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 T_1/2 = 1.10 ²⁵ 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.
