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 T_1/2 = 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.
