Synchrotron studies of narrow band materials

At the time of writing this report, we have had 3 weeks of beamtime on the Ames/Montana beamline at the Wisconsin Synchrotron Radiation Center (SRC), working with Cliff Olson. This run was devoted to a mix of high temperature superconductors, heavy-Fermion and related uranium materials, and some heavy Fermion and other rare earth materials. The high Tc materials are very difficult because only a small fraction of samples yield high quality photoemission spectra, even if they have good bulk superconducting properties, as is the case for our samples
