Thermoreflectance test of W, Mo, and paramagnetic Cr band structures

Abstract
We present a systematic investigation of the electronic structure of W, Mo, and paramagnetic Cr. Thermoreflectance has been used to test the most recent band-structure calculations. Analysis of the systematic trends and improvement of the experimental method allowed us to identify a number of new critical-point and Fermi-surface transitions. An unambiguous interpretation is given for most optical-absorption features in the 0.5<hν<5.0  eV photon-energy range.
