  A reconstruction technique based on Radon transforms is used to obtain 3D
electron momentum density rho(p) using nine recently measured high-resolution
Compton profiles (CPs) from a Cu_{0.9}Al_{0.1} disordered alloy single crystal.
The method was also applied to nine corresponding theoretical CPs computed
within the KKR-CPA first-principles scheme in order to show that our
reconstruction procedure reproduces rho(p) reasonably. We comment briefly on
how well a map of the Fermi surface (FS) can be obtained by folding the
reconstructed rho(p) into the first Brillouin zone.
