Description

The study of the 557.7 nm line profile of Oxygen perturbed by Argon is resumed using a semiclassical close coupling formalism. The radiative and collisional couplings are explicitly included and their effects are discussed. Comparison with the former quantum mechanical close coupling calculation by Julienne lay stress on the importance of trajectory effects

Abstract (French)

L'etude du profil de la raie a 557.7 nm de l'Oxygene pertube par l'Argon est reprise dans le formalisme semi-classique ou les differents couplages (radiatif et collisionnel) sont effectivement introduits et discutes. La comparaison avec les resultats quantiques (Julienne 1982) permet de mettre en evidence l'importance des effets de trajectoire
