Abstract

The method of angle- and spin-resolved photoelectron spectroscopy has been used in combination with a laser based source of vacuum ultraviolet (VUV) radiation to study the photoionization dynamics of the HI molecule. The narrow bandwidth (Δv<1 cm−1) of the ionizing VUV radiation (v=83 200 cm−1−89 300 cm−1) enables the resolution of the molecular rotation for single-photon excitation to spin-orbit autoionization resonances. The experimental results for the dynamical parameters σ,A, β, ζ, and α are compared to the results of a recent ab-initio calculation (M. Büchner, G. Raseev, and N.A. Cherepkov, J. Chem. Phys.96, 2696 (1992)) and used to analyze the photoionization process in terms of partial contributions of different values ofl and λ to the outgoing electron waves.
