K-shell x-ray production by 0. 5-2. 5-MeV /sub 4//sup 9/Be/sup +/ ions incident upon selected elements from fluorine to potassium

Journal Article · · Phys. Rev. A; (United States)
K-shell x-ray production cross sections are reported for /sub 4//sup 9/Be/sup +/ ions incident upon thin /sub 9/F, /sub 11/Na, /sub 13/Al, /sub 14/Si, /sub 15/P, /sub 17/Cl, and /sub 19/K targets. Incident-beam energies range from 0.5 to 2.5 MeV. It is found that the first Born approximation (plane-wave Born approximation plus the Oppenheimer-Brinkman-Kramers treatment by Nikolaev) greatly overpredicts the data, while the predictions of the perturbed-stationary-state theory with energy-loss, Coulomb deflection, and relativistic corrections (ECPSSR) are generally in good agreement with the data. There is a low-velocity discrepancy between the data and the ECPSSR predictions which may be due to multiple ionization effects on the fluorescence yields used to convert total ionization to x-ray production cross sections.
