Abstract

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 ⁴S⁰_3/2 ground state and the low-lying ²D⁰_3/2,5/2 and ²P⁰_1/2,3/2 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.
