Circular dichroism has been observed in the photoelectron diffraction of chemically shifted W 4f photoelectrons from the W(110)1{times}1-O surface. The diffraction peaks from first-layer W atoms bonded most directly to oxygen showed an azimuthal rotation similar to those reported in a prior experiment on Si(001). The maximum rotation angles are also in good agreement with those calculated using the formula {Delta}{phi}=m/kRthinspsin{sup 2}{theta} derived previously by Daimon {ital et al.} [Jpn. J. Appl. Phys., Part 2 {bold 32}, L1480 (1993)] and assuming m=4, which is the maximum magnetic quantum number of the photoelectron wave function. {copyright} {ital 1998} {ital The American Physical Society}
