Lattice dynamical properties of neptunium chalcogenides

Arya, Balwant Singh

Abstract

The phonon calculations of neptunium chalcogenides (NpX; X = S, Se, Te) based on breathing shell model (BSM) which includes breathing motion of electron of the Np-atoms due to f-d hybridization, have been performed. The significance of this approach in predicting the phonon properties of NpX compounds has been discussed and the role of f-electron has been examined. The model predicts that the short range breathing phenomenon plays a dominant role in the phonon properties. The specific heat for these compounds has been reported.
