摘要：

We report the observation of eight unexpected energy levels close to but clearly different from H2 B 1u+ levels. In transitions involving these levels vacuum-ultraviolet transitions terminating in p-H2 levels are observed subsequent to two-photon Q(1) excitation X1g+(v=0),EF g+1(v=6) of o-H2. Several findings indicate that these strange levels may be a manifestation of electronically excited H4, which has been discussed in a number of theoretical contributions. © 1990 The American Physical Society.
