An aerodynamic molecular beam and a phase-sensitive detection system were used to investigate the effects of the gas temperature, incidence angle, and surface temperature on the spatial distribution from 285 to 2500 degrees K argon beams reflected from an undefined copper surface. To determine the effects of the surface temperature on the spatial distribution, several experiments were run with a 0.54-ev incident beam at surface temperature of 285, 131, 77, and 36 degrees K. These data are the first known observations of lobular scattering patterns for low energy i.e., 0.30- to 0.54-ev beams scattered from contaminated surfaces at low temperatures.
