Abstract: Self-interaction of a light beam in compressed hydrogen was investigated experimentally by the schlieren method. The self-interaction was deduced from the change in the angular spectrum of the pump beam. The effect was found to be related to the change in the refractive index of H₂ resulting from the excitation of the molecular vibrations in the stimulated Raman effect.
