WebThis is the so-called phase problem of crystallography. Details of the methods to estimate phases go beyond the scope of this article. Direct methods rely on necessary characteristics of the electron density (e.g. always positive) and on resulting phase relationships that exist among sets of reflections, leading to a finite set of possible ...
