K-shell photoionization of oxygen
Gorczyca T.W.; Hasoglu M.F. (Institute of Physics Publishing, 2014)R-matrix calculations of the 1s photoionization in oxygen are reported. Proper treatment of spectator Auger broadening, relaxation, pseudoresonace elimination, and shake-up/shake-off are addressed. © Published under licence ... -
L -shell photoionization of Mg-like S4+ in ground and metastable states: Experiment and theory
Mosnier J.-P.; Kennedy E.T.; Cubaynes D.; Bizau J.-M.; Guilbaud S.; Hasoğlu, Muhammet Fatih; Blancard C.; Gorczyca T.W. (American Physical Society, 2022)We report measurements of the absolute photoionization cross sections of magnesiumlike S4+ over the 158-280 eV photon energy range. The experiments were performed with the multianalysis ion apparatus at the SOLEIL synchrotron ... -
Photoionization of atomic sodium near threshold
Gorczyca T.W.; Ballance C.P.; Hasoǧlu M.F.; Badnell N.R.; Manson S.T.; Savin D.W. (American Physical Society, May 2024)R-matrix with pseudostates (RMPS) calculations have been carried out for photoionization of atomic sodium near threshold. The large RMPS atomic orbital and configuration basis allows for very accurate computations of ... -
Photoionization of Xe@C60 using R-matrix methods
Gorczyca T.W.; Hasoglu M.F.; Manson S.T.; Ballance C.P. (Institute of Physics Publishing, 2014)We report Breit-Pauli and Dirac R-matrix cross sections for the photoionization of endofullerene Xe@C60, showing strong confinement resonances, in excellent agreement with a recent experiment. © Published under licence by ... -
Sulphur x-ray absorption in the local ısm
Gatuzz, Efrain; Gorczyca T.W.; Hasoglu M.F.; Costantini E.; García, Javier A.; Kallman, Timothy R. (Oxford University Press, 1 January )We present a study S K-edge using high-resolution HETGS Chandra spectra of 36 low-mass X-ray binaries. For each source, we have estimated column densities for S i, S ii, S iii, S xiv, S xv, and S xvi ionic species, which ...
