Synchrotron Radiation Photoemission Studies of Fe 3d States in Cd_{1-x}Fe_{x}Se

The angle integrated resonant photoemission measurements of Cd_{1-x}Fe_{x}Se were performed for different Fe concentrations (x = 0.00, 0.07, 0.14) in the photon energy range between 30 eV and 70 eV using synchrotron radiation. The ternary compound valence band photoemission spectra show, in comparison to the CdSe results, two additional structures, whose intensity depends on Fe content, which were assigned to Fe 3d states of e symmetry with spin up and down, respectively. The hybridization of the t_{2} component of the 3d electrons of Fe in the valence band is discussed.

The use of synchrotron spectromicroscopy in neurobiology is definitely beyond the feasibility-test stage. It produced a large variety of results, mostly concerning the microscopic localization of transition elements in neural cells. We will first describe the experimental technique, then we will discuss some specific experimental examples, including the uptake of cobalt and zinc in rat cerebellar neurons.
