Les spectres d'émission de 237Np dans des sources de 241Am : AmO2, AmAs et AmBi révèlent plusieurs états de charge des ions de recul ainsi que des atomes isovalents de neptunium en substitution dans les sites d'américium. Cette situation représente les conséquences des processus de recul et d'ionisation déclenchés par la désintégration α de 241Am. L'observation d'états ioniques définis et bien distincts indique un caractère non métallique pour tous ces composés. L'étude détaillée de la variation des spectres de AmO2 en fonction de la température permet de confirmer l'apparition d'un ordre magnétique dans ce composé vers 8 K ; aucune évidence pour l'existence d'une transition magnétique n'est obtenue dans AmAs et AmBi.The 237Np emission spec...
