Spectral and electron-collision properties of atomic ions. II. Inner-shell properties

In this report, a follow-up to our earlier paper [Theodosiou, Manson, and Inokuti, Phys. Rev. A 34, 943 (1986)] on comprehensive calculations of various properties of all atomic ions in all stages of ionization with nuclear charge Z{≤}50, we investigate, within the Hartree-Slater approximation, inner-shell properties including orbital binding energies, x-ray transition energies and rates, photoionization cross sections, and expectation values of powers of electron radial coordinates. Throughout we concentrate on enumerating general trends of the properties as functions of the nuclear charge Z and the total electron number N. The systematics thus found for highly stripped ions (i.e., for ions in which Z-N is appreciable) are interpreted in terms of the outer-shell screening and the hydrogenic shell structure in which complete shells occur at N=n(n+1)(2n+1)/3 =2,10,28,60,..., for principal quantum numbers n=1,2,3,4,..., respectively.
