MAXIMUM ENTROPY METHOD IN MOMENTUM DENSITY RECONSTRUCTIONL. Dobrzynski1, A. Holas2 1 Institute of Physics, Warsaw University Branch, Lipowa 41, 15-424 Bialystok, Poland 2 Institute of Physical Chemistry, Polish Academy of Sciences, Kasprzaka 44/52, 01-224 Warsaw, Poland The Maximum Entropy Method (MEM) is applied to the reconstruction of the 3-dimensional electron momentum density distributions observed through a set of Compton profiles measured along various crystallographic directions. It is shown that the reconstruction of electron momentum density may be reliably carried out with the aid of a simple iterative algorithm suggested originally by Collins. A number of distributions has been simulated in order to check the performance of MEM. It is shown that MEM can be recommended as a model-free approach. Close X |
