Abstract

The long standing Γ_n/Γ_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 (Γ_2N) in Γ_nm.
