10. In principle, one can also have a contribution to the ZEKE spectrum from direct absorption into the ionization continuum followed by the outgoing electron being captured, by the ionic core, into a high Rydberg state. In this capture process the excess kinetic energy of the electron is converted to excitation of the core. It is the inverse process to autoionization of high Rydberg states and it can also be observed directly [M. Tsukada, N. Shima, S. Tsuneyuki, and H. Kageshima, J. Chem. Phys. 87, 3927 (1987); T.
