The detection of 182Hf by Accelerator Mass Spectrometry (AMS) is greatly complicated because of the stable and common isobar 182W. Although significant W reduction can be achieved during negative ion formation using HfF5 -, additional separation is necessary to achieve detection sensitivities sufficient for astrophysical applications, i.e. detection of potential supernova-produced 182Hf on Earth. In this paper, we present a new development of isobar separation using the ?TOF detection method at... »
