Die Clausius-Mosottische Formel in der Theorie der Dielastika

Point defects in crystal lattices are specified with respect to their mechanical properties by the elastic polarisabilityα (dia-elastic case) or by the permanent elastic dipole momentp (para-elastic case) or by both together. These fundamental quantities can be obtained in macroscopic measurements of elastic moduli by applying formulae of the Clausius-Mosotti type and of the polar gas type resp. The present work gives the corresponding theory.
