Investigation of (α, pxn) reactions on natural iron

The stacked-foil activation technique and HPGe gamma-ray spectroscopy were used for the investigation of alpha-particle-induced reactions on natural iron up to 50 MeV. Excitation functions for the production of reaction residues 57 Ni, 56 Ni, 58 Co, 57 Co, and 56 Co from alpha-particle-induced reactions on 56 Fe were measured with a view to improve the quality of earlier measurements. The experimental results were compared with calculations considering equilibrium as well as preequilibrium reactions according to hybrid model of Blann (ALICE/90). It was found that the initial exciton configuration n 0 = 4(2p + 2n + 0h ) i.e., pure particle state appears to give a good fit to the experimental data.Résumé : Utilisant la technique d'activation de cibles superposées et la spectroscopie gamma HPGe, nous étudions les réactions induites dans le fer naturel par des particules alpha jusqu'à 50 MeV. Afin d'améliorer la qualité des mesures existantes, nous mesurons les fonctions d'activation pour la production des noyaux résiduels 57 Ni, 56 Ni, 58 Co, 57 Co et 56 Co générés par des particules alpha sur du 56 Fe. Nous comparons nos résultats avec ceux de calculs dans le modèle hybride de Blann (ALICE/90), en tenant compte des réactions à l'équilibre et prééquilibre. Nous obtenons le meilleur accord avec les données expérimentales lorsque la configuration pour l'exciton initial est l'état strictement à particules (sans trou) n 0 = 4(2p+2n+0h).
