In order to study recombination processes in gaseous nebulae, one requires the coefficients for radiative recombination to many excited states of neutral atoms and positive ions. These may be calculated as functions of electron temperature once the corresponding photoionization cross sections are known. For photoionization from valence-electron states a general formula has been obtained using a method which is an extension of that used by Bates and Damgaard for bound-bound transition probabilities.
