Abstract
Somewhat over a decade ago, researchers in Göttingen [2.1] and Saclay [2.2] discovered that it was possible to produce helium atomic beams with a velocity spread of well under 1%. Attainment of this unprecedented energy resolution (a fraction of 1 meV) made it feasible to explicitly resolve the small energy losses or gains which ensue through inelastic interaction of a helium atom with the vibrational modes of a solid surface. This immediately stimulated tremendous interest in the use of inelastic helium scattering to experimentally probe surface lattice dynamics [2.3]. The first measurement of a complete surface phonon dispersion curve was reported in 1981 [2.4], heralding a period of dramatic growth in inelastic helium scattering. Today there are about twenty high resolution helium beam machines in existence, distributed among a dozen groups worldwide. Single-phonon inelastic helium scattering has clearly found a niche.
