摘要
Debye-Waller factors of five h.c.p. elements (Ti, Zr, Ru, Tm, Hf) have been determined from X-ray diffraction intensities. Within the limits of experimental errors, the Debye-Waller factors associated with the two principal directions are equal. The Debye temperatures (theta (M)) have been evaluated. The energy of formation of vacancies (E-f) has been estimated from a semi-empirical relation between E-f and theta.
