Reassessment of 182Hf AMS measurements at VERA
The radioisotope182Hf (t1/2 = 8.9 Ma) is of great interest for astrophysical applications as a chronometer for the early solar system or as possible live supernova remnant on earth. However, AMS measurements of182Hf are seriously influenced by the presence of the stable isobar182W, which cannot be separated at typical AMS energies. Previous studies revealed a possible suppression of182W against182Hf by extracting the negatively charged pentafluoride HfF5- from the ion source, leading to a...[Show more]
