Full-solid-angle and site-specific photoelectron diffraction data have been obtained from interface W atoms just beneath (1{times}1) Fe and (7{times}14) Gd monolayers on W(110) by utilizing the core level shift in the W f4{sub 7/2} spectrum. A comparison of experiment with multiple scattering calculations permits determining the Fe adsorption site and the relative interlayer spacing to the first and second W layers. These Fe results are also compared to those from the very different Gd overlayer and from the clean W(110) surface. {copyright} {ital 1997} {ital The American Physical Society}
