Improved HULLAC atomic data for singly ionized lanthanides lower the energy levels and raise kilonova opacities by factors of 3-10 per element and roughly 1.5 for a lanthanide-rich mixture, broadly matching ab initio GRASP results.

Systematic opacity calculations for kilonovae -- II. Improved atomic data for singly ionized lanthanides
Improved HULLAC atomic data for singly ionized lanthanides lower the energy levels and raise kilonova opacities by factors of 3-10 per element and roughly 1.5 for a lanthanide-rich mixture, broadly matching ab initio GRASP results.
