A note on X-ray spherical wavefields in the Laue case for perfect crystals

Spherical wavefields in the Laue case are obtained under conditions in which the real part of the crystal structure factor is small or zero.

{\bb Z}-module defects in crystals

New kinds of defects can appear in crystals where the atoms and unit cell sit on the nodes of {\bb Z}-modules, i.e. on three-dimensional projections of N-dimensional lattices. These defects are the result of the symmetry breaking due to the projection of the structure from N to three dimensions. Examples are given that illustrate the processes. A new kind of dislocation, here called a `scalar dislocation', is expected; it generates no deformation and has no interaction with stress fields.
