Two- and three-body interactions and phonons in some f.c.c. metals
Description
Two- and three-body interactions in f.c.c. metals are derived from the general Morse potential. These interactions are employed to develope the dynamical matrix, which involves only three force constants. The dispersion curves for the f.c.c. metals like calcium, strontium, ytterbium, and lanthanum are derived from the elements of the matrix so developed. The predictions show good agreement with the recently measured phonon dispersion in the said metals. (author)
