ROTATIONALLY RESOLVED PHOTOELECTRON-SPECTROSCOPY OF AUTOIONIZING STATES OF WATER

Rotationally resolved photoelectron spectra are reported for rovibroni cally state-selected autoionizing levels of water. These photoelectron spectra are helpful for the spectroscopic assignment of the autoioniz ing-levels and provide considerable dynamical information on the mecha nisms for the transfer of energy and angular momentum between the ion core and the Rydberg electron. As a result of angular momentum restric tions, photoelectron spectra for J = 0 autoionizing levels provide a d irect partial wave analysis for the ejected photoelectrons.
