Facilities for the performance of Fano measurements as a probe of electron correlation
- UMR-MUST
Fano Effect measurements are the key to direct observation of the Kondo or spin shielding intrinsic to models of electron correlation. The Fano Effect is the observation of spin polarized photoelectron emission from NONMAGNETIC materials, under chirally selective excitation, such as circularly polarized photons. Below are described three spectrometers, with which Fano Effects measurements have been made. The key measurements are based upon spin-resolving and photon-dichroic photoelectron spectroscopy. True spin-resolution is achieved by the use of a Mini-Mott detection scheme. The photon-dichroic measurements include the variants x-ray magnetic circular and linear dichroism angular distributions (XMCDAD and XMLDAD). Both a multichannel, energy dispersive collection scheme as well as the spin-detecting Mini-Mott apparatus are used in data collection.
