Quick Reference

(RBS)

A technique for analysing samples of material by irradiation with a beam of alpha particles and measurement of the energies of the alpha particles after they have been scattered by the sample. This enables the elements present and their amounts to be determined because the energy of a scattered alpha particle depends on the mass of the nucleus with which it collides. RBS is used extensively in medicine and industry.
