Effect of isotope concentration on the lattice parameter of germanium perfect crystals
RC Buschert, AE Merlini, S Pace, S Rodriguez… - Physical Review B, 1988 - APS
The difference in lattice parameters between germanium crystals of natural isotopic
composition and an isotopically enriched crystal of Ge 74 was calculated and measured by
using a double-beam triple-axis x-ray spectrometer. The measured relative fractional
difference was (-6.3±0.3)× 10− 6 and (-14.9±0.3)× 10− 6 at room and liquid-nitrogen
temperatures, respectively. The corresponding calculated values are-6× 10− 6 and-12× 10−
6. The agreement is very good, given uncertainties in the values of physical constants used …
