14. One color experiments: Main emphasize on H + VMI (KER´s and angular distributions vs. Rydberg and ion-pair states and J´s) 2 E HBr (HBr + ) HBr* Ry H + Br - * Ion-pair 2xh  h  2xh  H + & (Br) + H * & (Br*)

15. Two color experiments: H + and Br+ VMI (KER´s and angular distributions vs. Rydberg and ion-pair states and J´s) 2 E HBr (HBr + ) HBr* Ry H + Br - * Ion-pair 2xh  2xh  h  H + (Br) + H + Br H + Br* H* + Br NB: Br = Br(3/2) & (1/2) H*+Br or H+Br* H + Br** H** + Br H + and Br + 1st color 2nd color For example

16. ERGO: Detect H, Br, H* and Br* by 2nd color, i.e. H(n=1) + 2h -> H*(n=2) …..+h -> H + + e: 2hn = 82 258.95 cm-1 / hn= 41129.48 cm-1 / =243.1346 nm H*(n=2) + h -> H*(n=3) …….+h -> H + + e: hn = 15233.15 cm-1 /  = 656.463 nm Br = Br(3/2) & (1/2); Br* = Bromine Rydberg states, for example https://notendur.hi.is/agust/rannsoknir/rempi/cf3br/Thesis-Kari-jan11.pdfhttps://notendur.hi.is/agust/rannsoknir/rempi/cf3br/Thesis-Kari-jan11.pdf, page 12 :
