Abstract
An alternative method for reconstruction of three-dimensional momentum dens ity from directional Compton profiles is proposed and successfully applied to theoretical data on magnesium oxide (with a random noise added). The met hod consists of obtaining a compact analytical model for the reconstructed n(p) from the least-squares fit directly on the directional profiles. The r esult is compared, together with a standard numerical-based reconstruction, to the theoretical momentum density from which the profiles were calculate d.
