Reconstruction of Momentum Density Distribution from 2D ACAR Data via Maximum Entropy and Cormack Methods

Abstract:

Novel application of Maximum Entropy method to the reconstruction of electron momentum density distribution from line projections is presented. Our new algorithm is applied to two dimensional angular correlation of annihilation radiation data in Gd. Reconstructed densities are in very good agreement with corresponding densities reconstructed by Cormack’s method.
