Physical Review Letters 37, no. 17: 1141-1145. doi:10.1103/physrevlett.37.1141.0031-9007http://nrs.harvard.edu/urn-3:HUL.InstRepos:29407068An x-ray standing-wave-field apparatus has been constructed that demonstrates an impurity atomic position resolution of ∼0.02 Å. The method is applied to the measurement of ion-implantation-induced lattice relaxation. It is pointed out that the method is also suited to determine surface impurity locations perpendicular to crystal surfaces.en-USJournal Article2016-11-1810.1103/PhysRevLett.37.1141
