2) examine the property, prominently an invariable redshift, of moving atom radiation as informed by the hydrogen canal ray experiment [1] of Ives and Stilwell performed at the Bell Labs in 1938 for a thorougher investigation of the associated anomalous Doppler effect then known.
In their experiment on fast moving hydrogen canal ray spectral emission[1], Ives and Stilwell let positively charged hydrogen ions [H.sup.+.sub.i] of mass [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] and charge [q.sub.i] (i=2,3) be accelerated into a canal ray of high velocity, v, across accurately controlled electric potential V correlated with v through the work-energy relation q V = 1/2 [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] [v.sup.2]; or
Thomson (see 1897) found himself interested in the canal rays that Goldberg had discovered a quarter-century earlier (see 1886).
