In this paper, we have described the X-ray divergent beam technique, i. e. the production of Kossel lines and their applications to the deter-mination of the orientation of single crystals and to the precision measure-ment of lattice parameters. we have also discussed some useful methods forthe analysis of transmission and back-reflection Kossel lines. Some problemsthat might be worth to be studied and discussed further are suggested.
