Investigation of Off-Shell Effects in Triton Binding-Energy Calculations with Nonlocal-Core Nucleon-Nucleon Potentials

Using the Faddeev formalism, a study of the off-energy-shell variation of the triton binding energy ($E_t$) is made. The results are indicative of the insensitivity of $E_t$ to the off-shell differences associated with the various nucleon-nucleon potentials considered, which are equivalent on the energy shell and vary mainly in the shape of their repulsive cores for $r\lesssim 0.5$ fm.
