“…For instance, calculations suggested that [145] atomic relaxations on the stepped Ag (410) and Cu(320) surfaces extend several layers into the bulk with a non-uniform character in damping magnitudes of interlayer relaxations. LEED analysis for Ag (410) initially suggested [146] that there was no measurable [128], Co [129], and Re [130] Fe-W, Fe-Fe [139] Fe(310) [140], Ni(210) [141] Al(001) [142] Ni, Cu, Ag, Au, Pt and Pd dimer [112] Ti, Zr [109] V [109] [148]. On the other hand, LEED measurements of Cu(320) revealed a 24% contraction for d 12 and 16% contraction for d 23 , followed by 10% expansion for d 34 .…”
