Absract

A methodology for measuring and taking into account the background in a single-crystal neutron experiment with a position-sensitive detector is proposed. This methodology makes it possible to increase the ratio of integrated intensities to the standard deviation I/σ(I) for diffraction reflections and thereby supplement the experimental dataset with weak reflections that previously did not meet the condition I/σ(I) > 3 and were not taken into account in crystallographic calculations. The methodology was tested on experimental data during structural studies of Cs4(HSO4)3(H2PO4) crystals on the MOND diffractometer at the IR-8 reactor of the National Research Centre “Kurchatov Institute.”
