Abstract
The static relaxation and the lattice dynamics of rectangular edges of quadratic bars of four rock-salt-structured alkali halides is calcula ted using a shell model. The relaxation includes a large-scale contrac tion of the bar as well as tip-localized microscopic static displaceme nts. The phonon spectra of relaxed quadratic bars are presented and mo des localized at the edges are identified.
