Abstract Synchrotron-radiation-excited angle-resolved photoemission and x-ray-absorption spectra for the (111) face of PtGa{sub 2} are presented, along with derived experimental dispersion relations. These bands are compared with those obtained from a theoretical band-structure calculation. The x-ray-absorption near-edge spectra agree with the calculated site- and symmetry-decomposed partial density-of-states curves, and electrons transfer from Pt to Ga in forming the PtGa{sub 2} compound. Extended x-ray-absorption fine-structure spectra of PtGa{sub 2} are analyzed to yield its structural parameters. The energy variation of the Pt 5d bands for PtGa{sub 2} shows atomiclike behavior in the photon energy range of 80 to 220 eV.
