THE first HI-REMPI data!: Dye: C540A https://notendur.hi.is/agust/rannsoknir/rempi/hi/PXP-260312ak.pxp

Is this I atomic line? Dye: C540A 70814.3 cm-1 Large I(I+)/I(HI+) http://www.raunvis.hi.is/~agust/rempisvaedidir/jcp109585698.pdf: Is this I atomic line? 70814.3 cm-1 Dye: C540A Large I(I+)/I(HI+) ratio! ..and seems to increase with J´(?) 70854 cm-1 https://notendur.hi.is/agust/rannsoknir/rempi/hi/PXP-260312ak.pxp

ERGO: one would indeed expect the I(I+)/I(HI+) Judging from E(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)
