La transition stochastique dans le système hamiltonien classique associé à l'atome d'hydrogène dans un champ magnétique intense est mise en évidence au moyen d'applications de Poincaré. Le résultat est discuté dans le contexte de la théorie générale de la destruction des tores. La découverte d'une troisième intégrale du mouvement lorsque l'énergie est inférieure à l'énergie critique peut permettre d'expliquer l'existence d'anticroisements exponentiellement petits des niveaux d'énergie lorsque le mouvement est régulier. Au-dessus de l'énergie critique, le mouvement stochastique est responsable de la structure irrégulière du spectre dans le régime d'inter-n-mixing. La régularité du spectre dans le régime des résonances quasi-Landau est associ...
