Elastic Scattering from Deuterium

Abstract

Scattering of elementary particles from deuterons at BeV energies is considered. Corrections to the Glauber theory, resulting from violations of its high-energy and small-momentum-transfer assumptions, are found significant for experiments already performed. The most important correction results from including the principal-value part of the propagator in double scattering. Triple and higher-order multiple scattering are calculated in a model and are predicted to be important at momentum transfers of $-t>\mathrm{}4\mathrm{}$ Be${\mathrm{V}}^2$. Available data on the energy dependence of the "screening correction" to deuteron total cross sections are shown to disagree with the Glauber theory, and a possible phenomenological treatment of that disagreement is discussed.
