摘要：

The presence of oscillatory structures in the atomic x-ray absorption background is reported for the first time for surface EXAFS of c(2x2)NiCu(100) and (2x3)N/Cu(110). The experimental data for N/Cu(110) are compared to FEFF7 calculations of the oscillating atomic background mu(0)(E). For the two systems it is found that the AXAFS peak in the Fourier transform increases by a factor of two as the N-atom is adsorbed closer to the surface plane.
