L’étude des mécanismes de formation et de destruction des anions moléculaires est devenu un champ d’intérêt prononcé après la détection récente de six anions moléculaires (C4H-, C6H-, C8H-, CN-, C3N-, C5N-) dans le milieu interstellaire.Dans les environnements interstellaires où la densité d’électrons est relativement importante, le canal principal de formation de ces anions devrait être l’attachement électronique radiatif. Mais il manque aujourd’hui des données expérimentales et théoriques permettant d’évaluer cette hypothèse. D’autre part, le photodétachement est la principale cause de destruction de ces anions dans les nuages diffus et les régions de photodissociation. Une approche basée sur un développement monocentrique est appliquée à...
