MECHANISMS OF THE NONMESONIC WEAK DECAY OF Lambda HYPERNUCLEI AND THE THREE-BODY PROCESS

Abstract

The long standing Gamma(n)/Gamma(p) puzzle of NMWD has finally been solved recently. It appears that the reason behind the puzzle was the universal quenching of nucleon yields from the prediction of one-nucleon induced (1N-)NMWD. We have shown that the quenching of nucleon yields can be explained only when we include a fairly large contribution of the three-body process (Gamma(2N)) in Gamma(nm).
