• We present the performances of a 330 g zinc molybdate (ZnMoO 4 ) crystal working as scintillating bolometer as a possible candidate for a next generation experiment to search for neutrinoless double beta decay of 100 Mo. The energy resolution, evaluated at the 2615 keV γ -line of 208 Tl, is 6.3 keV FWHM. The internal radioactive contaminations of the ZnMoO 4 were evaluated as <6 μBq/kg ( 228 Th) and 27±6 μBq/kg ( 226 Ra). We also present the results of the α vs β / γ discrimination, obtained through the scintillation light as well as through the study of the shape of the thermal signal alone.
