K X-ray production cross sections, K β/K α ratios, and radiative Auger ratios for protons impacting low- Z elements
Abstract
A Cockcroft-Walton accelerator was used to produce 50-300 keV protons to excite characteristic X-rays from thick targets of elements from Z=21 to 32, using an efficiency-calibrated Si(Li) detector equipped with an ultra-thin window. X-ray production cross sections were determined and compared with prevailing theories. Special attention was paid to accounting for the radiative Auger effects (RAE) in the analysis of the X-ray energy spectra. Ratios of RAE to K α and K β intensities, as well as K β/K α ratios, will be compared to theoretical values.
