DAMA/LXe results on Charge-Non-Conserving processes

2000 - With the detector filled with Kr-free Xenon enriched in 129Xe at 99.95%, new limits on the electron decay have been obtained for the channel e- → νe + γ (exposure of 2257.7 kg day):

τ > 2.0(3.4) x 1026 y at 90% (68%) C.L.

2003 - First limit on the possible CNC decay of 136Xe into 136Cs by using the data collected during 8823.54 h of measurements:

τCNC (136Xe → 136Cs) > 1.3 x 1023 y (90% C.L.).
