Title: PHOTOABSORPTION AND PHOTOIONIZATION CROSS-SECTIONS OF
GAS-PHASE GEH-4 AND RYDBERG STRUCTURES OF GEH-4 AND SIH-4

1993) : pp. 1530-1536.
Abstract: The photoabsorption and photoionization cross sections of
GeH4 from the ionization threshold to 1060 angstrom have been
measured using synchrotron radiation as the continuum light
source. The cross sections for the production of neutral
products in the same spectral region have also been determined.
Weak diffuse structures were observed in both the
photoabsorption and photoionization spectra. The steplike
ionization structures in the ionization spectrum were observed.
The adiabatic ionization potential was determined to be at
1177.6+/-0.5 angstrom which is in excellent agreement with a
value recently reported by Ruscic et al. [J. Chem. Phys. 92,
1865 (1990)] using a photoionization mass spectrometry
technique. Rydberg series in the 1060-1180 angstrom region
converging to the ground state of GeH+ have been tentatively
assigned. In addition, the assignments of Rydberg states of
SiH4 reported in the literature have been re-examined in light
of the recently reported ionization potential [Berkowitz et al.,
J. Chem. Phys. 86, 1235 (1987)].
