Public ISBD Titre : Mass and charge distributions in iron-induced nuclear reactions at 840 MEV Type de document : texte imprimé Auteurs : Merouane Charif, Auteur ; C. Alice, Directeur de thèse Editeur : University of Maryland Année de publication : 1986 Importance : 158 f. Présentation : ill. Format : 27 cm. Note générale : Thèse de Doctorat : Chemistry : États Unis, University of Maryland : 1986 Bibliogr. f. 159 - 167 . Annexe f. 169 - 192 Langues : Anglais (eng) Mots-clés : Chemistry  ;  Mass  distribution  ;  Charge  distribution  ;  Nuclear  reactions  ;  Kinetic  energy  loss Index. décimale : D001386 Résumé : Projectile-like fragments from reactions of 15 MeV/nucleon ⁵⁶Fe with targets of ⁵⁶Fe and ²³⁸U have been measured as a function of total kinetic energy loss. The mass and charge distributions for each fragment were determined with discrete resolution. The main detector system for the energy measurement was a large ionization chamber with 80 cm active thickness. The timing system consisted of two channel-plate fast timing devices (CPFTD) which were used as start and stop detectors. A timing resolution of 250 psec, a mass resolution of 0.8 mass units and a charge resolution of 0.4 charge units were obtained with this system. Data were analyzed as a function of energy loss by fitting a two dimensional Gaussian function to the neutron-proton distributions. Results are given for the measured data as well as estimates of the primary fragment distributions after correction for neutron evaporation. A comparison with low energy data (8.3 MeV/nucleon) is made. Mass and charge distributions in iron-induced nuclear reactions at 840 MEV [texte imprimé] / Merouane Charif, Auteur ; C.
