“…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.…”

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.

Photoionization Yield Spectra below the Atomic Ionization Limit in Xenon

Photocurrent yield and absorption spectra for xenon were measured as functions of pressure (p ^ 1 x 10 5 Pa) between -11.0 and 11.8 eV. With a pressure-independent yield function Y{hv) the photocurrent spectra can be calculated from the absorption spectra with the assumption of a "dead layer" at the surface of the LiF window. Y{hv) is roughly proportional to the number of atomic transitions with excitation energies between 11.10 eV and hv. This behavior can be explained with a simple statistical model for the decay of the Rydberg states.PACS numbers: 32.80.Fb, 33.80.EhRare gases are ideally suited to study basic processes in atomic and molecular systems. This includes Rydberg states, autoionization, dimer and excimer formation, and photoionization. A detailed knowledge of electronic excitation and the relaxation phenomena is of considerable theoretical interest but also has implications for the technical applications of rare gases, i.e., in excimer lasers and detectors. The ionization of rare gases has been studied recently by use of supersonic beams 1^3 and by multiphoton excitation with lasers. 4 Rare gases exhibit strong pressure effects in both fluorescence and ionization. Even at pressures as low as 40 Pa photoionization has been observed at photon energies that are considerably lower than the first atomic ionization potential of the rare-gas atoms. 5,6
