Abstract
A new, and non-destructive method of characterising obsidians for archaeological purposes is described. Sodium, fluorine, and aluminium are determined by inelastic scattering of a beam of protons from a 3 MeV Van de Graaff accelerator. Irradiation and counting are simultaneous and take five minutes per sample, while data analysis is automated and requires about 20 sec per sample.
