Many-body effects observed in the positron annihilation experiment
G. Kontrym-Sznajd, H. Sormann
This paper is devoted to study many-body effects in the positron annihilation experiment, both electron-positron (e-p) and electron-electron (e-e) correlations. Various theories of…
Different ways of dealing with Compton scattering and positron annihilation experimental data
G. Kontrym-Sznajd, M. Samsel-Czekala
Different ways of dealing with one-dimensional (1D) spectra, measured e.g. in the Compton scattering or angular correlation of positron annihilation radiation (ACAR) experiments ar…
Band structure of LaB6 by an algorithm for filtering reconstructed electron-positron momentum densities
G. Kontrym-Sznajd, M. Samsel-Czekala, M. Biasini +1
A new method (NM) for filtering three-dimensional reconstructed densities is proposed. The algorithm is tested with simulated spectra and employed to study the electronic structure…
On the reliability of various enhancement theories for a description of electron-positron densities in metals
H. Sormann, G. Kontrym-Sznajd, R. N. West
Four theoretical approaches to calculate momentum densities of electron-positron annihilation pairs (MDAP) in crystalline solids are confronted with 3D densities reconstructed from…
Three-dimensional reconstruction of the Fermi surface of LaB6
M. Monge, M. Biasini, G. Kontrym-Sznajd +1
The 2-dimensional angular correlations of the positron annihilation radiation (2D-ACAR) on a single crystal of LaB6 was measured for three projections. The 2D-ACAR spectra were sub…
Reconstructed Momentum Density and Fermi Surface in Cu0.9Al0.1
M. Samsel-Czekala, G. Kontrym-Sznajd, G. Doring +5
A reconstruction technique based on Radon transforms is used to obtain 3D electron momentum density rho(p) using nine recently measured high-resolution Compton profiles (CPs) from…
