Description

A calculation of the rho-meson self-energy in nuclear matter with use of realistic interactions is presented. No collective effects as predicted by Toki and Comfort are observed. This discrepancy is traced back to their use of a strong rho exchange. An analysis of realistic interactions (Reid, Bonn, Paris) shows that NN phase shifts uniquely specify a weak effective rho exchange for momentum transfers up to 3 fm-1
