HIGH-RESOLUTION STUDY OF LOW-LYING CORRELATION SATELLITES IN XENON

The technique of pulsed field ionization-zero kinetic energy photoelec tron spectroscopy, typically applied to the investigation of ionic sta tes of atoms and molecules resulting from single electron excitation, has been used to probe the correlation satellite states of xenon betwe en 23.6-24.7 eV. The resulting spectra show the formation of clearly r esolved satellite states with intensities of a similar magnitude to th at of the 5s5p(62)S(1/2) ionic state. This technique can be extended t o other atomic and molecular species to obtain the positions and cross sections for the formation of such states.
