High-resolution Compton Scattering as a Probe of Fermiology and Electron Correlation Effects

Compton scattering is one of the few spectroscopies which directly probes the ground state momentum density in materials. Recent progress in synchrotron light sources has brought a renewed interest in the technique as a tool for investigating fermiology related issues on the one hand, and as a unique window on hitherto inaccessible correlation effects in the electron gas on the other. We provide an overview of some of our recent work on a variety of metals and disordered alloys, including Li, $\mathrm{L}{\mathrm{i}}_{1-\mathrm{x}}\mathrm{M}{\mathrm{g}}_{\mathrm{x}}$, Be, Cu, $\rm Ni_{75}Cu_{25}$,$\rm Ni_{75}Co_{25}$, Al and Al-Li.
