Helium Atomic Data Sets

The following tables have the link to the files of energy levels, radiative transition rates, Collisional excitation cross sections, radiative recombination and photoionization cross sections, autoionization rates and Collisional ionization cross sections of Helium.

Each ASCII file contains values per ion stage NE(Number of Electron=2 for neutral atom) of element Helium : : Autoionization rates produced by fac.AITable
HeNEa.ce : Collisional excitation cross sections produced by fac.CETable : Collisional ionization cross sections produced by fac.CITable
HeNEa.en : Energy levels produced by the function fac.Structure
HeNEa.rr : Radiative recombination and photoionization cross sections produced by fac.RRTable : Radiative transition rates produced by fac.TransitionTable

He 1+    (Hydrogen like Helium) n/a He01a.ce He01a.en He01a.rr
He 0+ He02a.ce He02a.en He02a.rr
