Isobar separation of 32Si from 32S in AMS using a passive absorber

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, have published an article by Schlomberg et Al in which researchers have developed an accelerator mass spectrometry (AMS) method to detect 32Si and separate it from its intense isobar 32S; the experiments have been conducted at the Laboratory of Ion Beam Physics at the ETH Zurich.  The developed method aims to measure the half-life of 32Si.

Silson’s silicon nitride membranes were used for the Passive absorber method, the gas absorber entrance membrane had thickness 200nm and size 5 x 5 mm^2, and the detector entrance membrane has thickness 1000nm and size 10 x 10 mm^2
