In order to assign the experimentally observed bands to the particular modes, theoretical calculations using density functional theory (DFT) have been performed based on the structural data obtained by X-ray crystallography.

We find that the forward shifts of the momenta along the light propagation of the two photoelectrons are roughly proportional to their fraction of the excess energy.

But the severe volume change and structure transformation make their cycle stability and rate capability unsatisfactory.

Special attention is given to a quantitative determination of on-site and transferred hyperfine fields on the 61Ni nuclei.

We calculate the signal to noise ratio (SNR) of XPCS experiments from a concentrated lysozyme solution at the length scale of the hydrodynamic radius of the protein molecule.

At present, the energy resolution of these techniques can beimproved only by decreasing the spectral window of the involved optics—monochromators and analyzers—thereby sacrificing the intensity.
