Precision X-Ray Diffractometry Using Powder Specimens

摘要: Errors concerned with the geometry of counter tube diffractometer method, nature x-ray source, and technique collecting data are reviewed briefly. arising from imperfections in instrument misalignment source respect to were studied experimentally. The results presented discussed terms resultant error determination lattice parameter a cubic crystal. determined both analytically empirically relation extrapolation procedures commonly used for diffractometers. It is shown that, depending on construction instrument, effect gears may almost double final extrapolated value parameter. (P.C.H.)
