Evidence for L-dependence generated by channel coupling: O16 scattering from C12 at 115.9 Mev

Abstract

The inclusion of strong coupling to states of projectile and target nuclei for 115.9 MeV \nuc{16}{O} scattering from \nuc{12}{C} leads to an S-matrix which, when subject to $S_L\to V(r)$ inversion, yields highly undulatory local potentials. Previous work has shown that explicitly $L$-dependent non-undulatory potentials are equivalent to undulatory $L$-independent potentials with the same S-matrix. Here we show that $L$-independent equivalents for certain simple model $L$-dependent potentials exhibit undulatory features qualitatively similar to those arising from channel coupling for 115.9 MeV \nuc{16}{O} scattering from \nuc{12}{C}. We discuss the relevance to the question of $L$-dependence as a generic property of nucleus-nucleus interactions.
