Abstract
BAHCALL1 has pointed out that in the absorption line spectrum for ions in the gaseous envelope of 3C 191, there is a correlation between the ionization potential and Δz, the difference between z (the red-shift of the absorption line spectrum for any ion) and z̄em (the mean red-shift of the emission line spectrum). Fig. 1 indicates, as a set of vertical lines, the spread in Δz values derived from curves fitted by Burbidge and Lynds2 to four sets of measurements3,4. In the figure, the ionization potential plotted is that of the atom or ion having one more electron than the absorbing ion; while Δz is defined as z̄em−z.
