Abstract

A new lifetime limit on the charge nonconserving (CNC) electron decay through the channel electron into neutino+gamma has been established analyzing a 2257.7 kg day event sample collected by the about 6.5 kg liquid xenon DAMA scintillator at the Gran Sasso National Laboratory of INFN. This limit is tau>2.0(3.4) x 10^{26} yr at 90% (68%) C.L., one order of magnitude higher than the current limit for that channel.
