Improved Nearside-Farside Decomposition of Elastic Scattering Amplitudes
R. Anni, J. N. L. Connor, C. Noli
Abstract
A recently proposed technique is described that provides improved nearside-farside (NF) decompositions of elastic scattering amplitudes. The technique, involving a new resummation formula for Legendre partial wave series, reduces the importance of unphysical contributions to NF subamplitudes, which can appear in more conventional NF decompositions. Applications are made to a strong absorption model that arises in chemical and nuclear physics, as well as to a 16O + 16O optical potential at Elab = 132 MeV.
