Abstract
Le transfert d'excitation entre les atomes métastables d'argon et l'azote est étudié dans un dispositif de post-luminescence en écoulement. Nous trouvons un rapport de branchement entre les deux états N2(C3 Π u) et N2(B3 Πg) compris entre 0 et 1,3. Les valeurs trouvées sont nettement plus faibles que celles publiées par Setser (1970) : 6 ± 1. Nous donnons une limite supérieure des coefficients de transfert pour chaque niveau vibrationnel de N2(B3 Πg)Keywords
