Pressure dependence of ionic polarizabilities in crystals.

A program in Maple V is developed that allows for the calculation of polarizabilities of both anions and cations on the basis of a new method and of the extension of the one developed previously. Furthermore, an alternative way of evaluation of delta r(i)/delta p is given. Values of delta alpha(total)/delta p can be evaluated for a given salt even when experimental data at high pressures are not available.
