Based on the hard-sphere potential approximation, angular distributions of scattered particles at different mass ratios M1:M2 were calculated. The results were compared with experiments carried out with the following atoms:[Formula: see text]The sputtered particles from the target as well as from the incident-ion beam were collected on graphite rods and measured by either activation analysis or a radioactive tracer technique.

Thermal gas-release characteristics of copper single-crystal specimens bombarded by a high-energy Xe+ ion beam are presented. The influence of the crystallographic orientation of the targets bombarded, of the ion energy, and of the total ion dose was investigated. The ion energy ranged from 20 to 80 keV, and the total ion dose from 1013 to 1018 ions/cm2. Curves for fractional gas release were obtained by the method of stepwise thermal treatment, using the radioactive tracer technique. From the experimental data obtained and the theoretical expectations, corresponding activation energies for gas release were deduced. Thermal stability of the gas embedded in the target is discussed.

Transfer Testing

This paper outlines three procedures used to evaluate oxygen transfer under process conditions. Steady state procedures, a radioactive tracer technique and off gas methods are described and methods of calculation are outlined. Two case histories, an industrial waste site and a municipal site, are presented.
