Dipole-Dipole Hyperfine Constants and Lattice Relaxation of an Interstitial Defect in LiF

Abstract
A study of the lattice relaxation about an interstitial fluorine defect in LiF has been made. Following the method of Daly and Mieher, we have calculated dipole-dipole hyperfine constants for 10 lattice shells and have compared them with experimental constants obtained by electronnuclear double double resonance. The calculations show that most of the lattice ions relaxed away from the defect.
