The three‐dimensional electron–positron momentum density in aluminum is 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. On the basis of the experimental data, the Fermi surface topology, the high momentum components (HMC), the enhancement effect, and the autocorrelation function are discussed.
