The isotropic Compton profile difference across the phase transition of VO
Kari O. Ruotsalainen, Juho Inkinen, Tuomas Pylkkänen +4
We studied the isotropic Compton profile of the prototypical oxide VO across the temperature induced electronic and structural phase transition at T 340 K. We sho…
Resonant X-ray Emission Spectroscopy With a Standing Wave Excitation
Kari O. Ruotsalainen, Ari-Pekka Honkanen, Stephen P. Collins +6
The Borrmann effect is the anomalous transmission of x rays in perfect crystals under diffraction conditions. It arises from the interference of the incident and diffracted waves,…
Momentum distribution and Compton profile by the ab initio GW approximation
Valerio Olevano, Andrey Titov, Massimo Ladisa +3
We present two possible approaches to calculate the momentum distribution n(p) and the Compton profile within the framework of the ab initio GW approximation on the self-energy. Th…
Momentum Distribution and Renormalization Factor in Sodium and the Electron Gas
Simo Huotari, J. Aleksi Soininen, Tuomas Pylkkänen +9
We present experimental and theoretical results on the momentum distribution and the quasiparticle renormalization factor in sodium. From an x-ray Compton-profile measurement of th…
Electron momentum density in yttrium
G. Kontrym-Sznajd, M. Samsel-Czekala, A. Pietraszko +7
A simultaneous analysis of high-resolution directional Compton profiles and two-dimensional angular correlation of positron annihilation experimental data has been performed by stu…
Electrode thickness measurement of a Si(Li) detector for the SIXA array
T. Tikkanen, K. Hamalainen, S. Huotari
Cathode electrodes of the Si(Li) detector elements of the SIXA X-ray spectrometer array are formed by gold-palladium alloy contact layers. The equivalent thickness of gold in one e…
