Verifying DiffEXAFS measurements with differential X-ray diffraction.
Differential EXAFS (DiffEXAFS) is a novel technique for measuring atomic perturbations on a local scale. Here a complementary technique for such studies is presented: differential X-ray diffraction (DiffXRD), which may be used to independently verify DiffEXAFS results whilst using exactly the same experimental apparatus and measurement technique. A test experiment has been conducted to show that DiffXRD can be used to successfully determine the thermal expansion coefficient of SrF(2).
