K-shell photoionization of Na-like to Cl-like ions of Mg, Si, S, Ar, and Ca

M. C. Witthoeft, J. García, T. R. Kallman +4

We present $R$-matrix calculations of photoabsorption and photoionization cross sections across the K-edge of Mg, Si, S, Ar, and Ca ions with more than 10 electrons. The calculatio…
