A model is developed, enabling the intensities of diffracted beams to be calculated in closed form, starting from a pairwise (Yukawa‐type) interaction law between a gas atom and a solid atom. The treatment is more satisfying than most previous treatments, which calculate the diffracted intensities as functions of empirical parameters describing the over‐all gas‐solid interaction, without reference to the microscopic (pairwise) interaction. The model is illustrated by an application to the He–LiF system.
