Abstract
The excited state fractions of hydrogen isotopes in neutral beams are calculated from compact expressions for the rate coefficients and rate equations. The results are presented in a form suitable for beam emission plasma diagnostic interpretation. Comparisons with results in the published literature reveal discrepancies there up to a factor of two in some cases in the Hα emission rate or its density derivative.Keywords
