Program Description
X-ray Compton scattering measures electron density in momentum space ( i.e., electron momentum density), which contains information on the defining properties of electronic ground states. Our recent experiments have captured the images of valence orbitals and Fermi surfaces on the electron momentum density distributions, obtained for high-Tc cuprates [1], spin-crossover cobaltites [2], lithium manganites [3], and heavy fermion systems [4]. In this talk, we present the above results after an introduction to X-ray Compton scattering and its technique.
