THE ANOMALOUS SCATTERING OF X-RAYS BY BORON PHOSPHIDE AND ZINC SULFIDE
Abstract
The dispersion of the atomic scattering factors of Zn, S, and P in selected regions of the x-ray spectrum was investigated by measuring the differences in the intensities of Bragg reflections due to the anomalous scattering of x-rays by zinc sulfide and boron phosphide. Intensity differences among selected reflections occurring at identical Bragg angles, divided by the corresponding average intensities were plotted as funcions sin theta (the Bragg angle) and compared with 2 sets of theoretically predicted values of delta I/I sub average. Experimentally determined values of delta I/I sub average for zinc sulfide using Mo K sub alpha radiation were in good agreement with those from similar pre vious investigations and appear generally to be higher than the theoretically expected values, especially in the region of large Bragg angles. Similar disagreement between the calculated and experimentally observed values of delta I/I sub average was found for ZnS with copper K sub alpha radiation. Results indicate a need for revision of the dispersion corrections of Zn and S for Mo K sub alpha radiation, and also for Cu.
