Abstract
A general description of the instrumentation for accelerator mass spectrometry (AMS) at the Aarhus EN tandem accelerator is given, with special emphasis on AMS measurements of the radioisotope 32Si. It is shown how interference from the stable isobar 32S is avoided by injecting 32Si as the silicon trihydride ion 32SiH − 3 rather than 32Si −. The measurements demonstrate that isotopic concentrations of 32Si down to about 10 −15 may now be measured. The technique is applied in some examples where measurements have been performed on samples containing 32Si produced by: (a) the charged particle reaction 18O( 16O, 2p) 32Si, and (b) double neutron capture in 30Si.
