dc.description.abstract | The maximum-entropy method of image reconstruction is discussed in the context of the crystallographic phase problem. Entropy is the function to be maximized in a space of phases which has dimension equal to the number of structure-factor constraints. The function [integral] [1 - exp (-[rho]/[rho]0)] dV is proposed as a suitable one. An analogy between the phase problem and the spin-glass problem of condensed-matter physics is discussed. This analogy has instigated a study of the geometry of the entropy surface in the space of unknown phases for a simple model and preliminary results are presented. | en |
