The Debye temperatures of the face centred cubic metals. I. X-ray and neutron diffraction results

Abstract

It is shown that the variation of the Debye-Waller factors of silver, gold and lead with temperature can be described by means of the nearest neighbour central force pair interaction theory of Killean. Expressions for the temperature dependence of the Debye temperatures of six cubic elements are obtained from previous X-ray and neutron diffraction measurements, and the anharmonic pair potential has been derived in each case.
