Experimental band structure ofCu3Au

Angle-resolved photoemission experiments on ${\mathrm{Cu}}_3$Au{001} with synchrotron light in the range 12.5–46 eV are presented and evaluated to produce the band structure along Γ–X. The initial-band positions have been obtained by assuming free-electron-like final states. The experimental band structure is compared with a recently calculated band structure. Similarities and discrepancies are discussed.
