Is it possible that I observed changes of 10-5A+/-10-6A in d-space? Specifically, I am scanning my sample in Bruker diffractometer in Bragg-Brentano configuration with internal standard. The XRD experiment has done in-situ. The sample did not move between experiments, even not rotated. 2teta steps are 0.02deg, acquisition time for each step was 0.2sec and the detector is a multi-channel detector. I considered the random changes in the internal standard (peak at 12deg) of 10-6A as my error. The changes in the sample's reflected peak (peak at 14deg) was 10-5A.
Please note that my half step is only 2teta (obviously I can improve it) is 0.01 which means a 0.005deg in teta. Do you familiar with similar work that has been intended to determine changes of 10-5A in d-space?
