Abstract
Recent measurements of the elastic differential cross section in the backward direction in electron krypton scattering just above the inelastic threshold of 4p55s J = 2 state at 9.915 eV illustrated the importance of including absorption effects in any theoretical calculation. Subsequently, there have been theoretical predictions of a substantial reduction in the backward direction of the elastic differential cross section in electron krypton scattering in the intermediate energy range up to 100 eV when absorption is included. In this paper we present the first measurement of the elastic differential cross section for krypton in the backward direction in this intermediate energy range; these measurements are generally in good agreement with the recent theoretical predictions.
