Query: Improved Nearside-Farside Decomposition of Elastic Scattering Amplitudes   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.
