“…Presented here are measurements of L sub-shell x-ray production cross sections for proton impact on thick targets of Y, Zr, Nb, Mo, Rh, Pd, Ag and Sn in the 50-300 keV energy range. Previous measurements by others [3][4][5][6][7][8] in this energy range have only reported total L-shell cross sections for these elements. The results are compared with ECPSSR and ECPSSR-UA theory and with different atomic parameter databases, by use of the computer code ISICS [9,10].…”

L x-rays excited from thick elemental targets of Y, Zr, Nb, Mo, Rh, Pd, Ag and Sn by proton impact in the energy range 50–300 keV were measured with a high-resolution Si(Li) detector equipped with an ultra-thin window. The L sub-shell x-ray production cross sections were determined from a thick-target analysis of the x-ray yields. These were compared with the ECPSSR theory along with various atomic parameter databases and including modifications using the united-atom (UA) binding energy correction.

Total L-X-ray emission cross sections are measured for proton bombardment of thin and thick targets in a wide range of elements. The results are compared with the PWBA-theory. The introduction of corrections with respect to the Coulomb deflection of the particles and to the change of the binding energy of the target electrons improves the agreement between the calculated and measured result,s. It is established within the experimental error that the parametrized cross section for constant reduced projectile velocities does not depent on the target atomic number.Die Wirkungsquerschnitte der totalen L-Schalen-Rontgenemission werden fur Protonenbornbardement von dunnen und dicken Targets in einem grol3en Elementebereich gemessen. Die Ergebnisse werden mit der PWBA-Theorie verglichen. DieEinfuhrung vonKorrekturen bezuglich der Coulombablenkung der Partikel und der Bnderung der Bindungsenergie der Targetelektronen verbessern die ubereinstimmung zwischen bereohneten und gemessenen Ergebnissen. Es wird festgestellt, dal3 innerhalb des experimentellen Fehlers der parametrisierte Wirkungsquerschnitt fur konstante reduzierte Projektilgeschwindigkeiten nicht yon der Targetatomzahl abhangt.
