“…Doubly excited autoionization resonances for the S 4+ isoelectronic cases of Al + and Si 2+ [30] and photoionization spectra in the UV range for the Mg-like Al + ion [31] were also investigated theoretically. Experimental investigations of the 2p-subshell photoabsorption of the isoelectronic Al + and Si 2+ ions were carried out using the DLP technique [32,33] and for the Al + ion by the synchrotron photon-ion merged beam technique [34][35][36]. More recently, isoelectronic doubly ionized Si 2+ absolute cross sections and resonance structures were measured at relatively high spectral resolution at the SOLEIL syn-chrotron and compared to MCDF and RPA calculations [37].…”

We report measurements of the absolute photoionization cross sections of the magnesium-like S 4+ ion over the 160-270 eV photon energy range. The experiments were performed with the Multi-Analysis Ion Apparatus (MAIA) at the SOLEIL synchrotron radiation facility. Single and double ionization ion yields produced by the photoionization of the 2p subshell of the S 4+ ion both from the 2p 6 3s 2 1 S0 ground state and the 2p 5 3s3p 3 P0,1,2 metastable levels were observed, as well as 2s excitations. Calculations of the photoionization cross sections were carried out using Multi-Configuration Dirac-Fock and R-matrix codes and the results are compared with the experimental data.

Photoionization of the free and confined Mg (Mg@C60) have been calculated in the vicinity of the inner-shell 2p thresholds using R-matrix at the Breit–Pauli R-matrix level with a particular emphasis on the various resonance series leading up to the two lowest inner-shell thresholds and the changes resulting from the confinement. For free Mg, the calculated resonance positions agree well with NIST values, and a number of new resonances are identified. For confined Mg, the calculation was done for various depths of the confining potential well in order to follow the trajectories of the resonances as a function of well depth. The results for the well depth corresponding to Mg@C60 showed that most of the resonances moved to higher photon energy, as a result of the confinement, but a few moved to lower energies. This phenomenology was found to result from the fact that the 3p, 3d and 4s excitations are trapped by the confining potential well, while the higher excitations were not.
