We investigate the electromagnetic polarizabilities of a nucleon using the method of QCD sum rules. The diagrams in the operator product expansion are taken into account up to dimension 6. We find that the polarizabilities of a nucleon can be expressed by means of three new kinds of susceptibilities

## Abstract A sum rule of powers of phonon frequencies is derived generalizing a sum rule of squared frequencies given previously by Blackman, Brout, and Rosenstock. The connection of these sums with the moments of the frequency spectrum of the crystal is investigated by choosing gradually enlarged
