“…The model potential theory given by Oli [3] employs as many as ten parameters to predict the phonon dispersion in zirconium. The phenomenological studies due to Singh et al [4], Cavalheiro and Shukla [5], Kushwaha [6], Upadhyaya and Sinha [7], and Mishra and Kushwaha [8] have employed a large number of disposable parameters which necessitate an equal number of measured data particularly on phonon frequencies and elastic constants for their evaluation. The Keating method used by Menon and Rao [9] also employs a large number of parameters.…”

A realistic theoretical study to predict the phonon dispersion and binding energy of h.c.p. metals is developed. The total interaction among the constituents is divided into two parts, ion-ion part and electron-ion-electron part. The former part is expressed by the modified form of the generalized exponential potential (MGEP) developed by the present group. To highlight the characteristic features of the MGEP other similar potentials are compared. The latter part is represented by the modified Krebs scheme, involving the dielectric screening due to Vashista and Singhwi. These interactions are blended to develop a model for predicting the binding energy and the phonon dispersion of the scantily studied h.c.p. metals like thallium.
