J-resolved He I emission predictions in the low-density limit
R. P. Bauman, R. L. Porter, G. J. Ferland +1
Determinations of the primordial helium abundance are used in precision cosmological tests. These require highly accurate He I recombination rate coefficients. Here we reconsider t…

Theoretical He I Emissivities in the Case B Approximation
R. L. Porter, R. P. Bauman, G. J. Ferland +1
We calculate the He I case B recombination cascade spectrum using improved radiative and collisional data. We present new emissivities over a range of electron temperatures and den…
