Abstract: A new lifetime limit on the charge nonconserving (CNC) electron decay through the channel e(-)-->nu(e)gamma has been established analyzing a 2257.7 kg day event sample collected by the similar or equal to 6.5 kg liquid xenon DAMA scintillator at the Gran Sasso National Laboratory of INFN. This limit is tau>2.0(3.4)x10(26) yr at 90% (68%) C.L., one order of magnitude higher than the current limit for that channel.
