Full Description
High resolution helium atom scattering can be applied to
study a number of interesting properties of solid surfaces
with great sensitivity and accuracy. This book treats in
detail experimental and theoretical aspects ofthis method
as well as all current applications in surface science. The
individual chapters - all written by experts in the field -
are devoted to the investigation of surface structure,
defect shapes and concentrations, the interaction potential,
collective and localized surface vibrations at low energies,
phase transitions and surface diffusion. Over the past
decade helium atom scattering has gained widespread
recognitionwithin the surface science community. Points in
its favour are comprehensiveunderstanding of the scattering
theory and the availability of well-tested approximation to
the rigorous theory. This book will be invaluable to surface
scientists wishing to make an informed judgement on the
actual and potential capabilities of this technique and its
results.
