We investigate the possibility that both nonleptonic strange-particle and charm-particle decays can be understood in terms of one effective nonleptonic Hamiltonian H/sub eff/=H/sub 0/+H/sub COR/. H/sub 0/ is a usual four-fermion current-current interaction term and the H/sub COR/ is the color-radius interaction term. The color-radius interaction is known to explain the ..delta..I=1/2 rule in strange-particle decays. The effects of H/sub COR/ as well as those of final-state interaction on two-body charm-meson decays are examined. The theory is in qualitative agreement with all measured branching ratios. Predictions for charm-meson decays into two pseudoscalar mesons are presented.
