Description

The two-dimensional measurement of the angular correlation of the positron annihilation radiation (2D-ACAR) is a powerful tool to investigate the electronic structure of materials. Here we present the full three-dimensional Fermi surface obtained by temperature dependent 2D-ACAR measurements in combination with common reconstruction algorithms. Although copper is believed to be a well understood system we find discrepancies between measurement and recent ab-initio calculations.
