QUANTITATIVE DETERMINATION OF POLE FIGURES WITH A TEXTURE GONIOMETER BY THE REFLECTION METHOD

摘要

For different slit systems of a modern texture goniometry (typenSiemens) the X-ray intensity reflected from texture less plane samples has been measured as function of the tilt angle ρ and Bragg angle 0.nThe intensity curves obtained generally enable quantitative and almost complete pole figure determinations to be made with only one reflection recording, even for materials with high line density. Investigations on rolled uranium sheet with CuK radiation showed that for reliable chart records up to cp = 70 on reflections with an angular separation of only A (2©) = 0. 7, the vertical receiving slit must be limited to at least 1 mm when using a horizontal main slit of 0. 5 mm.
