WebSep 14, 2024 · X-ray Absorption Fine Structure (XAFS) Bruce Ravel is the lead scientist at the Beamline for Materials Measurement (BMM), a new, state-of-the-art experimental station at NSLS-II. The XAFS station uses a tunable, monochromatic, and moderately high energy X-ray beam (4.5 keV to 23.5 keV) for X-ray absorption spectroscopy measurements. Webbismuth (Bi), the most metallic and the least abundant of the elements in the nitrogen group (Group 15 [Va] of the periodic table). Bismuth is hard, brittle, lustrous, and coarsely crystalline. It can be distinguished from all other metals by its colour—gray-white with a reddish tinge. History
