cds-question@unistra.fratomic-physicsWe present multi-configuration Breit-Pauli AUTOSTRUCTURE calculations of distorted-wave photoionization (PI) cross sections, and total and partial final-state resolved radiative recombination (RR) and dielectronic recombination (DR) rate coefficients for the first six ions of the trans-iron element Se. These calculations were motivated by the recent detection of Se emission lines in a large number of planetary nebulae. Se is a potentially useful tracer of neutron-capture nucleosynthesis, but accurate determinations of its abundance in photoionized nebulae have been hindered by the lack of atomic data governing its ionization balance. Our calculations were carried out in intermediate coupling with semi-relativistic radial wavefunctions. PI and recombination data were determined for levels within the ground configuration of each ion, and experimental PI cross-section measurements were used to benchmark our results. For DR, we allowed {Delta}n=0 core excitations, which are important at photoionized plasma temperatures.2011A&A...529A.147Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/529/A147CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/529/A147https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/529/A147http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/529/A147https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/529/A147https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/529/A147http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/529/A147GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/529/A147/table1Configuration-interaction expansions used for each Se ionrecnoRecord number assigned by the VizieR team.
