The Debye-Waller factors and Debye temperatures of crystals are parameters of lattice dynamical interest. The experimental determination of these parameters by the X-ray diffraction technique is the objective of this work. A systematic study on the effect of lattice strain on the Debye-Waller factors of strained copper powders constitutes the theme of this experimental work. Strain is produced in copper by repeated grinding. After each spell of grinding, the X-ray diffractogram is recorded. The lattice strain and Debye-Waller factors are determined from the half widths and integrated intensities of the Bragg reflections. From the Debye-Waller factors the Debye temperatures of strained copper powders have been determined. From a relation between X-ray Debye temperature and the vacancy formation energy, the vacancy formation energy of copper as a function of lattice strain has been determined.
