Description
Techniques for the measurement of the 146Sm nuclide, which is known as an extinct nuclide on the present Earth, were developed in order to determine its half-life. The nuclide was produced in three reactions of 147Sm (γ, n) 146Sm, 147Sm (n, 2n) 146Sm, and 147Sm (p, 2n) 146Eu (→146Sm). The Sm fraction in the target was chromatographically purified to prepare α counting samples as hydroxide. The 146Sm/147Sm α-activity ratios in the samples were measured using a Si surface barrier detector. The 146Sm22+/152Sm23+ and 147Sm22+/152Sm23+ ratios were measured by accelerator mass spectrometry using the ECR-ATLAS-GFM system. The 146Sm ions were distinguished clearly from the other ions such as the abundant isobar, 146Nd in the samples.
