Evidence for anharmonic interactions in cadmium from elastic X-ray scattering
Abstract
X-ray intensity of the almost-forbidden reflexion 303 in cadmium has been measured and interpreted in terms of anharmonic vibrations through the one-particle potential formalism. The value α 33 = (0.13 ± 0.02) × 10 -12erg/ Å3 for the cubic anharmonic force constant, implying deviation from axial symmetry, is deduced from the data.
