Based on the relativistic plane-wave impulse approximation for quasielastic (p + (Combining right arrow above sign),p + (Combining right arrow above sign)′) and (p + (Combining right arrow above sign),n + (Combining right arrow above sign)) polarization observables, we provide quantitative estimates of nuclear medium modifications of the NN interaction. We employ a 40Ca target for proton energies ranging from 135 to 300 MeV at a momentum transfer of 1.97 fm-1. Compared to former calculations, we have generated new meson-exchange parameters for the relativistic NN amplitudes between 80 and 200 MeV. Finally, the results are compared to the limited available data.
