Local electron-electron interaction strength in ferromagnetic nickel determined by spin-polarized positron annihilation
We employ a positron annihilation technique, the spin-polarized two-dimensional angular correlation of annihilation radiation (2D-ACAR), to measure the spin-difference spectra of ferromagnetic nickel. The experimental data are compared with the theoretical results obtained within a combination of the local spin density approximation (LSDA) and the many-body dynamical mean-field theory (DMFT). W...
متن کاملNovel Structure Function for Photon Fragmentation into a Λ Hyperon and Transverse Λ Polarization in Unpolarized Electron-Positron Annihilation
The possibility is examined for the inclusive Λ in unpolarized electron-positron annihilation to be transversely polarized. Due to final-state interactions, there exists a novel structure function F̂ (z,Q) for the inclusive Λ hyperon (or any other baryons) production from the unpolarized time-like photon fragmentation, which makes contribution to the transverse Λ polarization in the unpolarized ...
متن کاملPositron annihilation lifetime spectroscopy in nickel ferrite and iron oxide nanopowders
In this study, a positron annihilation lifetime spectrometer was set up and its resolution was optimized. The spectrometer is a fast-slow arrangement with time resolution of 250 ps. To obtain lifetime components and their intensities from analyzing positron annihilation lifetime spectrum, the Pascual software is used. Positrons are from a source of radioactive 22NaCl with 20 μCi activity enclos...
متن کاملInfluence of Hydrogen Adsorption on the Electron Spin Polarization (esp) at a Ferromagnetic (i 10)-nickel Surface
The ESP determined through electron capture by small angle reflection of deuterons at well oriented Ni(110)surfaces is found to be influenced by H 2 adsorption. A coverage of one monolayer reduces the ESP from -96 -+ 3% to -8 ± 3%. The sign indicates predominance of minority spin electrons. Desorption of hydrogen from the nickel surface restores the original polarization measured at a clean (11...
متن کاملPrototype Graphs for Radiative Corrections to Polarized Chargino or Neutralino Production in Electron-Positron Annihilation
We present the contributions from all types of one-loop corrections to the scattering amplitude for the pair production of polarized charginos or neutralinos from polarized electron-positron annihilation. The contributions are classified in terms of “prototypes” distinguished by the number of particles inside the loops and their spins. The results are quoted in terms of the Veltman-Passarino fu...
