Experimental and theoretical photoionization cross sections for Se+ from 18 eV to 31 eV

Absolute Se photoionization cross-section measurements and Dirac-Coulomb R-matrix calculations are reported for the photon energy range 18.0 eV – 31.0 eV, which spans the ionization thresholds of the 4S03/2 ground state and the low-lying 2D03/2,5/2 and 2P01/2,3/2 metastable states. The determination...

Description
Summary:Absolute Se photoionization cross-section measurements and Dirac-Coulomb R-matrix calculations are reported for the photon energy range 18.0 eV – 31.0 eV, which spans the ionization thresholds of the 4S03/2 ground state and the low-lying 2D03/2,5/2 and 2P01/2,3/2 metastable states. The determination of the photoionization and recombination properties of n-capture element ions is motivated by their astrophysical detection and the importance of their elemental abundances in testing theories of nucleosynthesis and stellar structure.
