Separation of Trace Level Hafnium from Tungsten:  A Step Toward Solving an Astronomical Puzzle

182Hf (T 1/2 = 9 × 106 y) is believed to be formed by pure r-process during a supernova explosion, and therefore, the search for minute traces of 182Hf in the earth's crust is of great interest. Only accelerator mass spectrometry (AMS) is well suited for detecting such low levels of 182Hf. But...
