Conduction in non-crystalline systems

Abstract A summary is given of what is now known about the existence of localized states for electrons in three-dimensional disordered systems, and what can be conjectured about...

On the Theory of Excitation by Collision with Heavy Particles

1. It has been shown, in a well-known paper by Born and Oppenheimer, that in evaluating the energy levels of a molecule, the nuclei may be treated as fixed, or slowly vibrating,...

The Mechanical Properties of Metals

A description is given of edge and screw dislocations in a close-packed cubic lattice, which leads up to an account of the theory of Frank and Read of the origin of slip bands. ...
