Dielectronic recombination of heavy species: the tin 4p~64d~q?4p64d~((q?1))4f+4p~54d~((q+1)) transition arrays for q = 1?10

摘要

We summarize detailed calculations of dielectronic recombination rate coefficients for Sn~(4+) - Sn~(13+) using three approaches of differing degrees of complexity. These are: configuration-mixed Breit-Pauli using the AUTOSTRUCTURE code, bundled-nl using the Burgess-Bethe General Program (BBGP) and configuration-average (CA) using the DRACULA code. We describe the implications for the finite-density modelling of tin plasma sources for microlithography and tin markers for magnetic fusion plasmas as well as for heavy species in general such as Tungsten ions which are of great importance for magnetic fusion plasmas.
