This can be done at Diamond I23 beamline. https://doi.org/10.1016/j.nimb.2016.12.005 Best regards, Jan Dne 16.02.2019 v 18:49 Patrick Loll napsal(a): > S has about 0.56 anomalous electrons at 8 keV, whereas P has about > 0.44. This is a small difference between two weak signals—unlikely to > give a clear result.
