Different symmetry configurations for an interstitial in a hexagonal close packed lattice are studied. Their stabilities are discussed and calculations are performed by means of an interatomic potential which reproduces some properties of Mg. The defect lattice eigenfrequencies and eigenvectors are calculated within the Einstein and a cluster approximation.
