Pressure dependence of ionic polarizabilities in crystals

A program in Maple V is developed that allows for the calculation of polari zabilities of both anions and cations on the basis of a new method and of t he extension of the one developed previously. Furthermore, an alternative w ay of evaluation of partial derivativer(i)/partial derivative (p) is given. Values of partial derivative alpha (total)/partial derivative (p) can be e valuated for a given salt even when experimental data at high pressures are not available. (C) 2001 Elsevier Science Ltd.
