Unitary Group Approach to the Many-Electron Correlation Problem,nt neither a review nor an original article, and the references are handled accordingly. In the limited space-time at our disposal, we cannot but briefly outline the basic concepts and procedures, completely avoiding any proofs or derivations.

Experiments on systems of increasing complexity are being performed, and very often such additional information is necessary to fully interpret the measurements. Systems with a finite number of electrons may exist as isolated entities, like polyat

Inter-war Penal Policy and Crime in Englandt the heats of mixing for most combinations of metals are small compared with those in systems with covalent or ionic binding.. Consequently, there are a countless number of metallic solid solutions.. As you might expect these display a vast variety of thermal, electrical, mechanical and magnetic pr

Jean-Dominique Deuschel,Andreas Grevens discussion, we shall give a few examples to illustrate the theory, and the kind of accuracy one can hope to achieve in particular types of solid, with one-body potential theory. These examples have been chosen from calculations which the author has either been involved in, or of which he has intim

Attention and the Processing of Sentences,ch involves the use of an independent-electron formalism, but with a semi-empirically determined effective Hamiltonian designed to reproduce the effects of electron exchange and correlation. A variety of effective Hamiltonians have been used, ranging from pseudopotentials, chosen mainly on the basis

It is of interest and indeed also possible to make quantitative calculations of a number of cohesive properties such as cohesive energies, lattice constants, compressibilities, el
