## Abstract Starting from a perturbation theory for the free energy of disordered solids, the anomalous temperature dependence of the specific heat can be calculated. The model under consideration is based on the two common features of a large group of disordered solids, firstly, the distorted SRO,
The specific heat of antimony has been measured in the temperature region 13" to 70Β°K. l%e data are compared \vith a calculation based 01~ an anisotropic continuum model which distinguishes betwee "soft" and "hard" modes of vibrations in anisotropic lattices resembling "layer-like" structures.
