Abstract
The fast-slow coincidence technique has been used for the first time t o measure the electron half-life, obtaining a very simple way for extr acting noise background from real signals. In this paper we present a 986h measurement for the channel e(-) --> gamma + nu, realized in a la boratory practically without any cosmic-ray shielding and with common low-resolution BaF2 scintillators, obtaining a period of T-e > 3.15 x 10(21) yr. This result is analized in comparision with previous report s obtained in ultra-low background, massive and high resolution Ge det ectors located thousand meters underground. So, an extrapolation of th e limit that would be obtained under such conditions is evaluated.
