摘要: Photoemission from C60 chemisorbed on Ni(110) has been studied by one-photon photoelectron spectroscopy (1ppe) and two-photon (2ppe) with synchrotron radiation (SR) synchronized SR laser radiation. The 1ppe spectra are as a function of coverage. Significant peak broadening relative to the thick film features is observed for three leading valence bands. large width levels obtained monolayer system consistent changes physical structure due strong chemical interactions nickel substrate. 2ppe experiment demonstrates transient excitation (t2u,hg) level C60.
