||[[ https://ui.adsabs.harvard.edu/link_gateway/1997FizA....6..149B/PUB_PDF | Bhattacharyya ]] calculates the radiative recombination cross sections of electrons and protons, useful for determining the lifetime of ionized hydrogen produced by rocket plumes in high orbits.  The relative center of mass energies range from microelectronvolts to 10 electron volts in Figures 1 and 2.
