摘要：

We have calculated the intensities of the subordinate hydrogen lines formed during the recombination epoch at redshifts 800 less than or similar to z less than or similar to 1600. We show that an allowance for the angular momentum splitting of hydrogen atomic energy levels and the dipole transition selection rules can reveal absorption features in the cosmic microwave background recombination spectrum in the submillimeter wavelength range.
