Abstract

We report about the Milano experiment to measure the electron antineutrino mass from the study of the Re-187 beta decay end-point. We present the analysis of the data collected during the first measurement with an array of AgReO4 crystals. The total mass and measuring time are about 2.3 mg and 10830 h x det respectively, giving a total statistics of approximately 6 x 10(6) (187R)e beta decays. We also report the preliminary results of a new measurement aiming at understanding the radioactive background observed in the previous data.
