An experiment to study double-beta decay (DBD) processes in 94,96Zr using two Cs2ZrCl6 (CZC) crystal scintillators (11 g and 24 g) has been performed deep underground in the DAMA/CRYS setup at LNGS. These crystals have been studied in terms of chemical purity and internal radioactive contamination, scintillation and PSD performances. Their high radiopurity was confirmed by low-background measurements over 456.5 d which resulted in a counting rate of 0.17 (kg·keV·y) −1 at the Q2β value of 96Zr. Limits on different DBD modes of 94,96Zr were set at the level T1/2 ~ 1017 − 1020 y (90% C.L.). [ABSTRACT FROM AUTHOR] |
