We make a careful study about the nonrelativistic reduction of one-meson-exchange models for the nonmesonic weak hypernuclear decay. Starting from a widely accepted effective coupling Hamiltonian involving the exchange of the complete pseudoscalar and vector meson octets (π, η, K, ρ, ω, K \* ), the
The nonmesonic weak decay width of 12 Λ C hypernucleus has been evaluated within a nuclear matter formalism, using the local density approximation. In addition to the one-body induced decay (ΛN → nN ), it has been also considered the two-body induced decay (ΛN N → nNN). This second decay is originat
One of the most urgent issues in A-hypernuclear physics today is how to resolve the difficulty in explaining the total and partial decay rates mm = Tn + I?, and the ratio Tn/Tp in the nonmesonic weak decay (NMWD) of hypernuclei [l]. There have been a few theoretical treatments of this isuue: (1) var
