Abstract
Recently developed chiral effective field theory models provide excell ent descriptions of the bulk characteristics of finite nuclei, but hav e not been tested with other observables. In this work, densities from both relativistic point-coupling models and mean-field meson models a re used in the analysis of meson-nucleus scattering at medium energies . Elastic scattering observables for 790 MeV/c pi(+/-) on Pb-208 are c alculated in a relativistic impulse approximation, using the Kemmer-Du ffin-Petiau formalism to calculate the pi(+/-) nucleus optical potenti al.
