摘要
Using scanned-energy mode photoelectron diffraction we show that in the Pd{111} (root 3 x root 3)R30 degrees-CO phase fee hollow sites are occupied with a carbon-Pd layer spacing of 1.27 (+/-0.05) Angstrom. This agrees very well with a relatively early LEED result of the Somorjai group and indicates that the experimental problems associated with applying scanned-energy mode photoelectron diffraction to second row transition metal substrates are not insurmountable.
