- Abstract
- Four beamlines completed, and to be completed by RIKEN are introduced in terms of their characteristics, accomplishment, and future perspective. Status of two biostructural beamlines (BL45XU and BL44B2) are for user operation. Physics beamline I (BL29XU) started commissioning, but to be extended as a 1 km beamline by the end of FY 1999. Physics beamline II (BL19XU) will be completed as the first long undulator beamline in SPring-8 in autumn 2000.

- Abstract
- High energy XAFS studies of Sm : K-edge in Sm2Fe17Nx with x=0.0, 0.5, 1.07, 1.55, 1.85, 2.04 and 3.0 were carried out at room temperature. In the XANES region, we firstly found the change of the shape near the absorption edge jump. It was considered that this change was due to the change of the Sm electron state by nitriding. In the results of the Fourier transformation of the XAFS oscillations, it was supposed that the local structure of Sm atom also changed by nitriding.
