| Research Abstract |
Since 2007, we have developing a novel method of isotopic analysis for multiple elements, such as noble gases, Mo and so on with ECRIS-MS equipped at RIKEN. We have successfully measured the isotopic compositions of Kr, Xe and Mo with high accuracy and precision. Especially, for Mo, the isotopic composition in iron materials has been able to be analyzed with sputtering methods equipped in ECR ion source.
