Ultraviolet Pumping of Hyperfine Transitions in the Light Elements, with Application to 21 cm Hydrogen and 92 cm Deuterium Lines from the Early Universe

We present new analytic calculations of the coupling between ultraviolet resonance photons and the population of the hyperfine states in the light elements (H, D, and super(3)He super(+)), which include several previously neglected physical processes. Among these are the backreaction of resonant sca...
