摘要

The 1 3Δg state of Na2 has been studied extensively by both filtered fluorescence and ionization detection and analyzed by both Dunham-type expansion and near-dissociation expansion (NDE) models in the analysis. Our observations have covered 99.998% of the potential well depth with the outermost Rydberg-Klein-Rees (RKR) turning point at 28.02 Å. NDE analysis gives Te=28 032.468 (±0.021) cm -1, De=7162.436 (±0.021) cm-1, and Re=3.463 81 (±0.000 28) Å. Significant long-range behavior in the near dissociation levels has been observed. Fitting of the RKR turning points gives the long-range coefficients C5=1.388 (±0.031)×106 cm-1 Å5 and C6=0.4008 (±0.0046)×108 cm-1 Å6. These newly observed results show reasonable agreement with recent theoretical calculations.
