Development of CaMoO4 crystal scintillators for a double beta decay experiment with Mo100

We have studied the energy resolution, α/βα/β ratio, temperature dependence of the scintillation properties, and the radioactive contamination of CaMoO4 crystal scintillators. We have also examined the use of pulse-shape discrimination to distinguish γγ rays and αα particles. A high sensitivity experiment to search for the 0ν2β0ν2β decay of Mo100 using CaMoO4 scintillators is discussed.
