Abstract

We extend the results of Bakalov et al. (Phys. Rev. Lett. 84, 2350 (2000)) on one-photon electric dipole transition line shift and broadening to the case of two-photon transitions. As an example, we consider the laser-induced transition in antiprotonic helium produced in a helium gas target. The transition is between antiprotonic helium states (n, l) = (33, 32) and (31, 30).Nous étendons les résultats de Bakalov et al. (Phys. Rev. Lett. 84, 2350 (2000)) sur le déplacement et l’élargissement de ligne de la transition dipolaire à un photon au cas des transitions à deux photons. Comme exemple, nous examinons la transition induite par laser dans l’atomcule d’hélium antiprotonique produit dans une cible d’hélium gazeux. La transition est entre les états (n, l) = (33, 32) et (31, 30).
