Role of Electron-Electron Interaction in the Theory of Positron Annihilation in Metals. III

In our previour paper with the above title an equation of motion for the electron-positron pair was derived with some approximations; here a modified equation for the pair is derived. This has the feature that in “RPA” the “reduced vertex functions” appear in a symmetrical way. We also derive an expression for the positron self-energy and explicitly show that the electron...

Positronium Formation in Interacting Electron Gas*)

A two-body bound state equation for a positron and an electron in an interacting electron gas is rederived, using a Green's function decoupling scheme and various approximations required to define a bound state are explained. The equation has some new features not discussed before, and the solution rules out the formation of positronium-like state at metallic densities. But the...

Spin Flip Scattering of Conduction Electrons from Impurities

Recent experiments on the spin flip scattering of conduction electrons by nonmagnetic impurities in certain metals have established that the scattering cross section does not increase monotonically with the charge (valence) of the impurity. It is suggested here that this may be due to a “resonant scattering” of the electron by the impurity potential (the term ‘resonant’ being...
