For Sr II, Plane-Wave Born and Distorted Waves approximations reproduce R-matrix effective collision strengths within an order of magnitude (DW within a factor of 2.5), offering cheap atomic data for kilonova nebular modeling.
We find that our AS transition rates underestimate the NIST values by about 10%, while the results from [18] overestimate them by 10%
