Abstract

A model is presented which extends the Glauber-theory description of meson scattering from deuterons to regions in which the meson-nucleon cross section varies rapidly or resonates. A Watson form of multiple-scattering theory is employed to derive a model which includes effects caused by the nucleons' Fermi momenta, nonforward intermediate scattering, and off-energy-shell scattering. It is concluded, after a numerical analysis, that the Glauber theory itself could generate the large oscillations in r2d reported in the analysis of π+d data around 1 GeVc and could introduce small peaks into the deduced I=0 channel of the K+n cross section. Nevertheless, conclusions drawn by following the usual folding procedures are not altered significantly by this model, for the K+d data of Cool et al.
