抜粋

The three dimensional electron-positron momentum density in niobium has been reconstructed from measurements of two dimensional angular correlation of positron annihilation radiations (2D-ACAR) followed by the image reconstruction technique based on a direct Fourier transformation. We determined the position of the Fermi surface sheets; Γ-centered hole octahedron, multiply connected jungle-gym arms and TV-centered hole ellipsoids. The Fermi surface topology is in good agreement with the theory.
