Résumé
On montre que l'intensité IR de la diffusion Raman de la lumière de 4He liquide est sensible en même temps à la structure à courte portée du liquide et à la partie à courte portée de l'interaction entre la lumière et deux atomes d'hélium. L'IR calculée en utilisant le modèle théorique le plus réaliste est de 40 % plus grande que la valeur donnée par l'expérience.
Abstract
It is shown that the Raman intensity IR form liquid 4He is sensitive to both the short-range structure of the fluid and the short-range part of the interaction of the light with two He atoms. The calculated IR for the most realistic model is 40 % larger than experiment.
