The off-shell behavior of the effective $t$ matrix is shown to be important. Density dependence of the effective interaction is also analyzed.REVTeX, 7 pages, 3 figures, minor correctionsNuclear TheoryNuclear ExperimentTesting of various parametrizations of effective nucleon-nucleon interaction in elastic and inelastic scattering of polarized protons from $^{12}$Ctext
