I atomic line:

Page 21: HI Absorption REMPI references (slide 9) Energetics (slides 10-)

Judging fromE(v´=0) is very close to V(v´=m+6), which is slightly higher in energy:

http://www.raunvis.hi.is/~agust/rempisvaedidir/jcp109585698.pdf

ERGO: one would indeed expect the I(I+)/I(HI+)ratio to increase with J´ (see slide 19)

Page 22: HI Absorption REMPI references (slide 9) Energetics (slides 10-)

The first data are promishing, indeed!
