Comparison between BEFS and EXAFS analysis for micro crystalline study of rhenium metal

BEFS can be used for the study of microcrystalline structure by means of microcalorimetric detectors. To evaluate the precision and the reliability of this new method we performed a comparison with EXAFS analysis. For this purpose the K-edge EXAFS measurement on rhenium metal have been done at the European Synchrotron Facility. The preliminary results indicate that BEFS analysis allows measuremet of the interatomic distances with resolution of hundredths of Angstroms, comparable to EXAFS.
