Dear All, if I well understood JFC correction is perfect in case of parallel incident beam; so, in case of conventional Bragg-Brentano diffractometer, shouldn't it work well only in case of use of Goebel Mirrors, that get incident beam exactly parallel? And is it true that using Goebel Mirrors and

Dear Larry, When you removed the soller slits leading to increased the axial divergence, which profile function is appropriate to model this, especially at low angle where the asymmetry is very stark? Kind regards William On 30 May 2006, at 16:01, Larry Finger wrote: [EMAIL PROTECTED] wrote:
