Abstract :
A new investigation of ββ decay modes in 134Xe and in 136Xe is presented. The data have been collected deep underground at the Gran Sasso National Laboratory of the INFN over a period of 8823.54 hours with the ≃ 6.5 kg DAMA liquid xenon pure scintillator, filled by Kr-free xenon containing 17.1% of 134Xe and 68.8% of 136Xe. New limits are set for various decay modes.
