| Abstract: | Term values for the 1s 2s states of H– are calculated with the use of simple eigenfunction approximations constructed on the basis of available Hartree-type functions for the 1s
2 and 2s
2 states of the ion. The results seem to support a tentative identification of the interstellar diffuse absorption bands at  4890 and 6180 as due to negative hydrogen. |
