Abstract
We report the observation of eight unexpected energy levels close to but clearly different from levels. In transitions involving these levels vacuum-ultraviolet transitions terminating in p- levels are observed subsequent to two-photon Q(1) excitation (v’ ’=0)→EF (v’=6) of o-. Several findings indicate that these strange levels may be a manifestation of electronically excited , which has been discussed in a number of theoretical contributions.
