| Citation Info: | Rydberg energy levels of the xenon diatomic excimer (Xe2) are probed in the afterglow
of a xenon discharge by photoexciting Rydberg ! Rydberg transitions of the molecule and monitoring the suppression of the second continuum emission (See document for equation). Energy levels lying »18210 cm−1 (549 nm) and 12500-14800 cm−1 (675-800 nm) above the minimum (Te) of the metastable a3§+u (1u) state correlated, in the separated atom limit with Xe(6s3P2 + Xe(5p6 1S0)), are studied in detail. Spectra obtained in the 675-800 nm range have been analyzed and the following spectroscopic
constants associated with the Xe2 (5)1g electronic state have been determined: (See document for equation). The spectra have tentatively been
assigned to transitions between the (1)1u and (5)1g states of the molecule. Cross sections
were measured and determined to be 10−17 cm2 for molecular features in the 675-800 nm
range, and 8·10−17 cm2 for an atomic feature at 823.2 nm. |
