A new red shift mechanism with possible applications to astrophysical problems such as quasars

A new red shift mechanism is proposed based on a succession of hyperfine atomic Raman interactions of a photon with hydrogen atoms. The possibility that this atomic Raman effect may be the cause of any given astronomically observed red shift can be observationally tested as follows. The hydrogen 21 cm line from the same source willnot be shifted by this hyperfine interaction (since it is a resonance process), while visible and ultraviolet lines are shifted.
