Abstract
High‐sensitivity single‐ionization efficiency functions of Xe have been measured using a computer‐controlled beam of electrons monoenergetic to ∼45 meV FWHM. Well‐defined structure detected in the energy range 12.2–13.5 eV is attributed to the excitation of neutral Xe Rydberg states converging on XE+(2P1/2) followed by autoionization. Some of the structure appears to correspond to parity forbidden s–p′ transitions. A sharp increase in ionization is observed at the 2P1/2 threshold.Keywords
