Testing atomic collision theory with the two-photon continuum of astrophysical nebulae
F. Guzmán, N. R. Badnell, M. Chatzikos +3
Accurate rates for energy-degenerate l-changing collisions are needed to determine cosmological abundances and recombination. There are now several competing theories for the treat…

H, He-like recombination spectra II: -changing collisions for He Rydberg states
F. Guzmán, N. R. Badnell, R. J. R. Williams +3
Cosmological models can be constrained by determining primordial abundances. Accurate predictions of the He I spectrum are needed to determine the primordial helium abundance to a…
