HIGH-RESOLUTION EXPERIMENTAL-DETERMINATION OF THE ANGULAR-DISTRIBUTION AND SPIN POLARIZATION OF XENON 7D' AND 9S' PHOTOELECTRONS AND COMPARISON WITH THEORETICAL RESULTS

Using narrowband tunable linearly br circularly polarized VUV radiatio n an examination of the dynamical parameters describing the autoioniza tion process of atomic xenon was performed. With a resolving power of similar to 10(5) in the excitation step a fully resolved determination of the position, magnitude and shape of the angular distribution and integral spin-polarization resonances was possible for the low Rydberg orders n=7 and n=9 of the d and s series, respectively. Comparisons a re drawn between the experimental data and some theoretical calculatio ns published in recent years. [S1050-2947(98)00108-5].
