    "abstract": "We propose the no-recoil approximation, which is valid for heavy systems, for\na double folding nucleus-nucleus potential. With this approximation, the\nnon-local knock-on exchange contribution becomes a local form. We discuss the\napplicability of this approximation for the elastic scattering of $^6$Li +\n$^{40}$Ca system. We find that, for this system and heavier, the no-recoil\napproximation works as good as another widely used local approximation which\nemploys a local plane wave for the relative motion between the colliding\nnuclei. We also compare the results of the no-recoil calculations with those of\nthe zero-range approximation often used to handle the knock-on exchange effect.",
