Abstract

The present paper deals with a new interaction potential energy function of the form

[math]

where C and p are constants. This new form though empirical has been found to yield the acceptable behaviour of the potential energy and force curves of alkali halides. Moreover, it has accurately reproduced the values of the parameters Di, E, γ and δ in the case of twenty diatomic halides.
