Positron annihilation spectroscopy is particularly suitable for studying vacancy-type
defects<? format?> in semiconductors. Combining state-of-the-art experimental and …

Publisher Summary This chapter discusses two major developments that have taken place
over the past decade. First is the enormous wealth of energy band calculations that have …

This review is concerned with the utilization of the positron-electron annihilation
phenomenon in studies of the physics of condensed matter. A preliminary chapter outlines …

Positron decay curves in various metals have been measured, using careful sample
preparation techniques and a delayed-coincidence system with 0.30-nsec (full width at half …

The recent development of the technique of inelastic x-ray scattering to study the electron
momentum distribution in the scatterer is surveyed. The simple relationship between the …

Quantum Monte Carlo calculations of the relaxation energy, pair-correlation function, and
annihilating-pair momentum density are presented for a positron immersed in a …

This article presents a simplified treatment of the high density, collisionless, free-electron
gas, based on the ideas of a wave number and frequency-dependent conductivity and …

A kinetic equation is proposed that leads, in equilibrium, to the Van der Waals equation of
state. It is shown that this kinetic equation obeys an H theorem, and that its equilibrium …

Details of the ground-state electron momentum density in Li, Be, B, LiF, Na, Mg, and Al have
been investigated by means of high-resolution Compton line-shape measurements. A sharp …

The angular correlation of the two gamma quanta emitted when a thermalised positron
annihilates with metallic conduction electrons is investigated by applying the newly …
