Molecular beam scattering - A means for studying the properties of solid surfaces
Abstract
The paper describes some possible means of deriving data on the interaction potential of particles with a surface by scattering experiments. In particular, a method based on inelastic scattering of particles on a surface is described. Li(+) ions with kinetic energy in the range 2-20 eV were scattered on well-defined single crystal surfaces, and the angle and energy distribution of the in-plane scattered ions were measured. Time-of-flight spectra were measured for various paths of the scattered ions and converted to energy spectra. The particle energy was sufficiently large so that the residence time of the particle in the repulsive zone of the potential was sufficiently short that the collision process could be described as a collision with a single surface atom with complete neglect of the binding of the atom with its neighbor.
