The sensitivity of proton-nucleus elastic scattering to different nucleon-nucleon effective interactions is studied within the framework of the nonrelativistic full-folding model. Calculations of the nucleon-nucleus optical potential are made using the free nucleon-nucleon {ital t}-matrices generated from the Bonn, Paris, Hamada-Johnston, and Melbourne nucleon-nucleon potentials, whose full off-shell behavior is treated explicitly. Applications are made to {ital p}+{sup 40}Ca elastic scattering at energies of 200, 300, and 400 MeV within the full-folding framework. Calculations using the on-shell {ital t}{rho} model have been made for comparison. Both full-folding and {ital t}{rho} results show comparable sensitivity to the particular choice of effective interaction, demonstrating the importance of a realistic description of the nucleon-nucleon interaction both on and off the energy shell.
