Rutherford Backscattering Spectrometry and Nuclear Reaction Analysisitate quantitative, standardless analysis. RBS is based on elastic Coulomb scattering between the projectile and the target nuclei, and is usually applied to obtain data for most if not all elements present in the specimen. In contrast, NRA is based on nuclear reactions which are element specific. T

Reflection High Energy Electron Diffraction RHEED as a diffraction technique for clean single crystal surfaces. The main reasons for this neglect was that RHEED gives quantitative results only on extremely flat surfaces which were not easily prepared and offered no theoretical advantages over LEED in the central surface science question of t
