Abstract. Kahana-like enhancement effect and the electronic structure of Zn have been studied. The measurements have been carried out using twodimensional angular correlation of annihilation radiation 2D-ACAR technique. The electron densities in momentum space ρ(p) and in wave vector space n(k) have been constructed using Fourier transformation and LCW folding procedure, respectively. In ρ(p) spectra, the reciprocal lattice points have emphasized the calculations. They have been argued in view of facets of Fermi surface of Zn. Furthermore, enhanced contributions nearby Fermi boundaries have been realized. It has interpreted in view of many body effects. In addition, Fermi surface has been evaluated in terms of free electron model FEM, radiofrequency size effect RFSE measurements and the band structure calculation using Pseudo-potential method and augmented plane wave APW method. The current Fermi surface measurements showed qualitative agreement to FEM and APWmethod. Generally, it reveals good accordance to APWmethod, especially in Fermi sheets’ dimensions.
