Abstract
Evidence for a molecule-substrate hybridized state near the Fermi leve l E-F is presented for Pd(110)-c(4 x 2)-benzene. Observed images of ad sorbed benzene near E-F by scanning tunneling microscopy consist of tw o elongated protrusions separated by a single nodal depression with C- 2 symmetry. The existence of a benzene derived state near E-F is also observed by metastable atom electron spectroscopy, and it is assigned to the antibonding states between the 1e(1g) molecular orbital of benz ene and the Pd 4d orbitals by ab initio molecular orbital calculations .
