Contained events in the Mont-Blanc nucleon stability experiment
Abstract
The nucleon-stability experiment (NUSEX) underway at Mt. Blanc Laboratory is briefly described, and some preliminary results are reported. NUSEX is designed to both generate nucleons and detect eventual nucleon decays, and comprises 136 1-cm-thick iron sheets interleaved with limited streamer tubes and arranged in a 3.5-m cube; the active mass for nucleon decay is about 130 tons. During 22,350 h of live time (equivalent to 2.3 x 10 to the 32nd nucleon yr) up to April 1985, 30 contained events were recorded (22 attributed to numu and seven attributed to nue), corresponding to a neutrino interaction rate of 149 + or - 27/kton yr.
