It is shown that the use of the Schrödinger equation may lead to the ab initio determination of the positions of the nuclei in a crystal, given a limited number of diffracted-beam intensities. In particular, it is shown that an extremely simplified

In most algorithms of direct methods, the variables are the normalized structure factors (SF) E n. An alternative set of variables is proposed which provides more flexibility for handling, in a single algorithm, phase relationships and direct-space c
