Photostimulated molecular admixture diffusion in semitransparent amorphous solids

A model is proposed for calculation of molecular gas admixture concentration in infinite semitransparent solid layer subjected to thermal radiation. Action of radiation upon a solid is expressed by ponderomotive forces and energy absorbed per unit mass of solid matrix and admixture. Absorption coefficient of a layer is accepted a sum of those of matrix and admixture. Numerical calculations for either two-atomic or three-atomic admixture present in a layer were carried out.
