K αx-ray satellite intensities with proton impact on Al to Fe at a fixed scaled velocity

Abstract

The $K\alpha$ x-ray satellite intensities were measured with proton impact at a scaled velocity (relative to that of the $L$-shell electron) $V_L=2.1\mathrm{}$ for $Z=13-20\mathrm{}$ and $V_L=1.0\mathrm{}$ for $Z=20-26\mathrm{}$. The intensity ratios $\frac{I_{K,1L}}{I_{K,0L}}$ are found to be well characterized by multiple-Coulomb ionization predictions. Taking into account the fluorescence yields, the comparisons of the measured intensity ratio with the corresponding ratio of theoretical vacancy cross sections yield a set of empirical vacancy-rearrangement correction factors. Theoretical estimates of these factors based on the atomic transition rates of McGuire are in reasonable over-all agreement with the extracted values.
