In
this work, Morse potential parameters of bcc crystals have been
calculated based on the calculation of volume per atom and atomic number
in each elementary cell, as well as the energy of sublimation, the
compressibility and the lattice constant. They are used for studying the
anharmonic interatomic effective potential, local force constant in
XAFS (X-ray Absorption Fine Structure) theory. Numerical results for Fe,
W and Mo are found to be in good agreement with experiment and with
those of other theories.
