概要

• 論文の詳細を見る

• The three dimensional electron-positron momentum density in niobium has beenreconstructed from measurements of two dimensional angular correlation of positronannihilation radiations (2D-ACAR) followed by the image reconstruction techniquebased on a direct Fourier transformation. We determined the position of the Fermisurface sheets; f-centered hole octahedron, multiply connected jungle-gym arms and.N-centered hole ellipsoids. The Fermi surface topology is in good agreement with thetheory,[positron annihilation, momentum density, Fermi surface, experiment, 2D- 1l ACAR, three dimensional reconstruction, niobiumf
