17. Experiments:

18. THE first HI-REMPI data!:
Dye: C540A

19. Is this I atomic line? Dye: C540A 70814.3 cm-1 Large I(I+)/I(HI+)
Is this I
atomic line?
cm-1
Dye: C540A
Large I(I+)/I(HI+)
ratio! ..and seems to
increase with J´(?)
70854 cm-1

20. NIST (http://www.nist.gov/pml/data/asd.cfm ):
I atomic line:
1.5
0.5
exp. Peak
NIST ( ):
i.e.
5s25p4(1D2)6p, 2[1]°, (J=3/2) <-<- 5s25p5  2P° (J=1/2)
and
(5s25p4(3P0)7s,  2[0] , (J=1/2) <-<- 5s25p5  2P° (J=1/2))
The latter of which should not be allowed (s <-<- p)

21. 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:
ERGO: one would indeed expect the I(I+)/I(HI+)
ratio to increase with J´ (see slide 19)

22. The first data are promishing, indeed!
