On the detectability of the hydrogen 3-cm fine-structure line from the epoch of reionization
A soft ultraviolet radiation field, 10.2 < h? < 13.6 eV, that permeates neutral intergalactic gas during the epoch of reionization (EoR) excites the 2p (directly) and 2s (indirectly) states of atomic hydrogen. Because the 2s state is metastable, the lifetime of atoms in this level is r...
