Author(s): H.-J. Lin, Y. Y. Chin, Z. Hu, G. J. Shu, F. C. Chou, H. Ohta, K. Yoshimura, S. Hébert, A. Maignan, A. Tanaka, L. H. Tjeng, and C. T. Chen<br/>We present a combined experimental and theoretical investigation on the orbital occupation and local symmetry of Co in Na_{x} CoO_{2} . We have carried out polarization dependent Co−L_{2,3} soft x-ray absorption spectroscopy measurements. By comparing the spectra with the results of configuration-...<br/><img src="http://prola.aps.org/graphics/free2read30x30.gif" width="30" height="30" alt="Free to Read"/><br/>[Phys. Rev.
