Abstract
We study the possibility of rho-delta mixing via N-N excitations in dense n uclear matter. This mixing induces a peak in the dilepton spectra at an inv ariant mass equal to that of the delta. We calculate the cross section for dilepton production through the mixing process and we compare its size with that of pi-pi annihilation. In-medium masses and mixing angles are also ca lculated.
