A quantitative study of the radiation damage of protein crystals by an intense monochromatic X-ray beam from a third-generation synchrotron radiation source is described at cryogenic temperatures between 40 K and 150 K. It is confirmed that primary radiation damage is independent of temperature. However, at higher doses the quality of data acquired at 40 K is superior to those at 100 K, apparently due to the temperature dependence of secondary and tertiary radiation damage and to reduced thermal motion.

The present high-resolution photoelectron study of Heusler-type Fe2VAl confirms the predicted density of states, in particular, the existence of a pseudogap at EF in its bulk electronic structure, which may cause its semiconductor-like conductivity behaviour at high temperatures, and suggests its electronic structure is highly sensitive to the local structural modification.
