N2 - The neutron-rich isotope 182Hf with its half-life of 9‘2 million years was alive in the early solar system and has been used to study the early development of the Earth and the Moon through isotopic anomalies of its stable decay product 182W. In addition, 182Hf may also complement a few other radionuclides in the million-year half-life range to trace relatively recent stellar events with high neutron fluxes in the vicinity of the Earth. This may be accomplished by finding measurable traces of live 182Hf in suitable terrestrial archives. With accelerator mass spectrometry (AMS) it should be possible to detect minute amounts of 182Hf. We will show that the main interference for the detection, the stable isobar 182W, can be significantly reduced by using HfF 5- ions. The AMS detection method of 182Hf and first results from Hf control rods of a recently retired research reactor are presented, which encourage us to search for naturally produced traces of 182Hf on Earth.
