Abstract:

Electron impact excitation functions have been measured in xenon for excitation of some of the 6p, 6p, 7p, 8s, 5d, and 8d levels. A one centimeter diameter electron beam was used to excite the gas atoms. The beam was made nearly mono-energetic by use of the retarding-potential-difference method. Most of the xenon I excitation functions were sharply peaked around 18 eV. Broader excitation functions were measured which had peak cross sections at electron energies around 30 eV. Cascading from higher energy levels showed significant effects on selected optical excitation functions. The electron gun produced a current of approximately one milliamp. Measurement of some xenon II excitation functions produced by simultaneous ionizationexcitation were obtained. The xenon II excitation functions demonstrated a maximum at approximately 35 eV, and a broader shape than the Xe I excitation functions.
