We propose an oscillation mechanism for meson mixing that causes charge symmetry breaking in nucleon-nucleon interactions. The mixing probabilities of the {rho} meson component in the {omega} meson and vice versa are estimated in a nuclear medium by using the data of the branching ratio B({omega}{r_arrow}2{pi}) and proton-proton (p-p) and neutron-neutron (n-n) scattering lengths. It is shown that the mixing probability depends on the nuclear density and is very small at normal density. In a nuclear medium, {rho}-{omega} mixing is larger in the p-p interaction than in the n-n interaction because of Coulomb repulsion. {copyright} {ital 1997} {ital The American Physical Society}
