Neighboring lanthanides and actinides with the same valence are recognized as a chemically similar group of elements because there is almost no difference in their ionic radii and the electron configuration in the outermost shell is identical. Our research group has been conducting experiments to induce selective oxidation reactions of targeted elements through multiphoton excitation, in which dipole forbidden f-f transitions followed by allowed f-d transitions are continuously induced. In this presentation, we focused on the oxidation reaction of Am(III), and has detect the oxidation reaction of Am(III) by irradiating Am(III) with a precisely tuned short-pulse laser.
