The authors are deeply indebted to all the people, both in Czechoslovakia and abroad, who have helped to compile the individual entries. Special thanks are due to Mr.
Skala for the excellent typing and technical assistance in producing the manuscript. The authors also thank the Editorial Board of the journal "Metallic Materials" for continuous encouragement.
Especially, for low-symmetry systems Brillouin zones zona de brillouin sometimes difficult to visualize, and another choice of unit cell may be useful, e. The Brillouin zone boundary consists of pieces of Bragg planes.
Since zona de brillouin points on the boundary may differ by a reciprocal lattice vector, only a part of the boundary may be used for characterization of states. There is no simple rule for that choice.

Dispersion curves at the zone boundary have either a maximum or minimum there or they merge with other curves giving rise to a change of degeneracy. Bragg plane perpendicular zona de brillouin and going through the midpoint of the line connecting the origin and K.
As a result, the first Brillouin zona de brillouin is often called simply the Brillouin zone. A related concept is that of the irreducible Brillouin zone, which is the first Brillouin zone reduced by all of the symmetries in the point group of the lattice point group of the crystal.
