Abstract

Scintillation properties of calcium molybdate are investigated. The emission spectrum is broad with a maximum at 520 nm. At room temperature the light yield is 4% of CsI(Tl) (400 photoelectrons/MeV) and the decay time is 17 μs. During cooling the light yield and decay time increase. Prospects of optimization of this scintillator are also discussed. The feasibility of the material for the search of neutrinoless double beta decay of 100Mo is analyzed. A half life limit of T1/2 = 1 · 1025 years (68% CL) seems feasible with CaMoO4 scintillator, running with 10 kg of 100Mo for 5 years. The background due to two neutrino double beta decay of 48Ca is also considered. Requirements for new scintillators for double beta decay search are formulated.
