Description
182Hf with half-life of about (8.90 ± 0.09) Ma is an extinct radionuclide and can only be produced by a supernova explosion in nature. 182Hf is one of a few radionuclides in the million-year half-life range for tracing a possible supernova event in the vicinity of the Earth within the last 100 million years. This may be accomplished by finding measurable traces of live 182Hf in suitable terrestrial archives. With accelerator mass spectrometry (AMS), an ultra-sensitive nuclear analytical technique, it is possible to detect minute amounts of 182Hf. The detection method of 182Hf with HI-13 AMS system at China Institute of Atomic Energy (CIAE) and the chemical procedures to reduce 182W interference are presented
