High resolution helium atom scattering can be applied tostudy a number of interesting properties of solid surfaceswith great sensitivity and accuracy. This book treats indetail experimental and theoretical aspects ofthis methodas well as all current applications in surface science. Theindividual 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 pastdecade helium atom...
