Abstract

In this study, new calculations of the excitation functions of 56Fe(p,2n)55Co,58Fe(p,2n)57Co,60Ni(p,n)60Cu,62Ni(p,2n)61Cu, 68Zn(p,2n)67Ga, 72Ge(p,n)72As,82Kr(p,2n)81Rb, 124Xe(p,2n)123Cs, 112Cd(p,2n)111In and 203Tl(p,3n)201Pb reactions have been carried for incident proton energies up to 50 MeV. In these calculations, the pre-equilibrium and equilibrium effects have been investigated. The pre-equilibrium calculations involve the newly evaluated geometry-dependent hybrid model, hybrid model and the cascade exciton model. Equilibrium effects are calculated according to the Weisskopf–Ewing model. The calculated results are compared with the experimental data taken from the literature.

Kurzfassung

In diesem Beitrag werden die Berechnungen der Anregungsfunktionen von56Fe(p,2n)55Co, 58Fe(p,2n)57Co, 60Ni(p,n)60Cu, 62Ni(p,2n)61Cu,68Zn(p,2n)67Ga,72Ge(p,n)72As,82Kr(p,2n)81Rb, 124Xe(p,2n)123Cs,112Cd(p,2n)111In und 203Tl(p,3n)201Pb Reaktionen bis zu einer Energie der einfallenden Protonen von bis zu 50 MeV beschrieben. In diesen Berechnungen wurden Pre-equilibrium- und Equilibrium-Effekte untersucht. Die Pre-equilibrium-Berechnungen beziehen das neu bewertete Geometrie-abhängige Hybridmodell, das Hybridmodell und das Kaskaden-Excitonen-Model mit ein. Die Equilibrium-Effekte werden mit Hilfe des Weisskopf–Ewing-Modells berechnet. Die Rechenergebnisse werden verglichen mit den experimentellen Daten aus der Literatur.
