“…In view of the gerade character of the Xe 2 ground state such studies have produced ample information about its ungerade excited states. 4,6,9,12,14,16 Gerade excited states, which can only be reached in a two-photon process 5,7,8,10,11,13,15 involving high-intensity lasers, have received considerably less attention.…”

“…In contrast, information on gerade excited states with a Xe 1 S 0 ϩXe* (6s←←5p) dissociation limit is still scanty. 7,8 The two gerade excited states occurring in the energy region near the Xe 1 S 0 ϩXe* 6s[3/2] 1 dissociation limit, viz., 1 g and 0 g ϩ , have been addressed in previous experimental studies. 7,8 These experiments have been carried out in a gas cell at ambient temperature with fluorescence detection.…”

Low-lying gerade electronically excited states of the Xe dimer, viz., 1 g and 0 g ϩ , with a Xe 1 S 0 ϩXe* 6s[3/2] 1 dissociation limit have been investigated using two-photon resonance enhanced multiphoton ionization techniques. High resolution is achieved by using this method in combination with a supersonic expansion. Moreover, the mass-resolved ion detection used in the present experiments has led to the observation of both vibrationally well-resolved spectra and continuous features, allowing the bound and dissociative parts of the excited states to be investigated separately. All spectra have been measured under both linearly and circularly polarized excitation conditions, enabling an unambiguous assignment of the signals. On the basis of FranckCondon calculations information on the potential energy curves of the bound and dissociative parts of the excited states has been obtained.

“…The atomic transition is actually two photon unallowed, and hence the oscillator strength is small, but experiments have shown that the excimers can be excited to the· upper region of their wells in this manner. 90,91 In addition, the UV intensities used in these experiments are very high (> 10 11 watts/cm 2 ), near the breakdown point of the solvent. It is not known how the oscillator strength of this partially allowed process compares with that of the three photon ionization process, but it is likely that the two photon process will dominate.…”

“…The 1st continuum at 152 nm is due to radiative transitions from the vibrationally excited (0 [7,12]. The two continua are thus produced by two different VUV emission processes whose kinetics accounts for the observation that at low pressure (P < 2 · 10 4 Pa) lumiscence is due to the 1st continuum, whereas it consists of the 2nd one for P > 5 · 10 4 Pa [13].…”

We present an investigation of the Xe2 excimer emission spectrum observed in the near infrared range about 7800 cm −1 in pure Xe gas and in an Ar (90%) -Xe (10%) mixture and obtained by exciting the gas with energetic electrons. The Franck-Condon simulation of the spectrum shape suggests that emission stems from a bound-free molecular transition never studied before. The states involved are assigned as the bound (3)0 + u state with 6p [1/2]0 atomic limit and the dissociative (1)0 + g state with 6s [3/2]1 limit. Comparison with the spectrum simulated by using theoretical potentials shows that the dissociative one does not reproduce correctly the spectrum features.
