NATO Advanced Study Institute on Direct Methods in Crystallography

Erice, 24 March to 6 April 1974

Purpose of the Course
Within the last few years there has been a rapid developmentof the so-called "direct methods" for solving crystal structures in Crystallography. These methods, based on mathematical relationships between the phases of the X-ray diffracted beams, are particularly amenable to automation and computer programs now exist which can solve structures with seventy, or even more, equal atoms in the asymmetric unit.

This Nato Advanced Study Institute will have as its goal the presentation of direct methods starting from first principles and building up to the latest developments in the subject. Formal lectures will be complemented by discussion and practical classes and the instructors will include most of the internationally-recognized authorities in the field.
