Thermoreflectance studies of bulk samples of V, Nb, Ta, and ..cap alpha..-phase TaH/sub x/ are reported and the results interpreted in terms of recent band calculations. The first interband transition is identified as a transition involving the ..sigma.. band at E/sub F/. An M/sub 3/ critical-point transition is attributed to states at N. Significant changes induced by interstitial hydrogen in solid solution ..cap alpha..-TaH/sub x/ are observed and interpreted as due to hybridization and lowering of the N/sup prime//sub 1/ eigenenergy.
