Description

K-shell X-ray production cross sections of Si, Ti, Cu and Ag were measured for incident protons, 4He and 14N ions in the energy range of 0.17<=E1/A1<=2 MeV/amu. The experimental ionization cross sections are compared with calculations according to the simple Plane Wave Born Approximation (PWBA) theory as well as the corrected PWBA model (PWBABC). Strong deviations of the experimental cross sections from the Z21 scaling are observed and discussed quantitatively. (orig.)

Abstract (German)

Die Wirkungsquerschnitte fuer die Roentgenstrahlenbildung von Si, Ti, Cu und Ag in der K-Schale wurden fuer auftreffende Protonen, 4He- und 14N-Ionen im Energiebereich von 0,17<=E1/A1<=2 MeV/amu gemessen. Die im Versuch ermittelten Ionisatiosquerschnitte werden mit Berechnungen nach der einfachen 'Plane Wave Born Approximation (PWBA)'-Theorie und nach dem korrigierten PWBA-Modell (PWBABC) verglichen. Erhebliche Abweichungen der im Versuch ermittelten Wirkungsquerschnitte von der Z21-Hochrechnung werden festgestellt und quantitativ diskutiert. (orig.)
