Expand description

The hydrogenic 2p (L2, L3) optical oscillator-strength density per electron, df/dW in eV⁻¹, at energy loss energy_ev for a subshell of binding energy binding_energy_ev: Karzas and Latter, Astrophys. J. Suppl. 6, 167 (1961), eqs. (36), (37) and (38) for n = 2, ℓ = 1 (the s and d continua together), converted by Salvat, arXiv:2605.22442, eq. (6.2) (module docs, “The formulas used”). Zero below the edge; at the edge, its limit (11 · 2¹⁰/(9B)) e⁻⁸.
