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≲0.5 fm.
