80-270 AA. Photoexcitation of the iodine 4d subshell was found to dominate the spectrum,
giving rise to discrete 1 A 1 to 1 A 1, 1 E transitions and a giant 4d to epsilon f continuum
resonance. An analysis of the transitions is given and a value of 1.72+ or-0.05 eV deduced
for the 4d 3 2/-4d 5/2 spin-orbit splitting in the iodine atom.
