    "abstract": "We show that even moderate excess of neutrons over protons in nuclear matter,\nsuch as in ${}^{208} Pb$, can lead to large $\\rho$-$\\omega$ mixing at densities\nof the order of twice the nuclear saturation density and higher. The typical\nmixing angle is of the order of $10^o$. The mixing may result in noticeable\nshifts of the positions and widths of resonances. We also analyze temperature\neffects and find that temperatures up to 50 MeV have practically no effect on\nthe mixing.",
