[ccp4bb] Resonant Scattering Directionality

2019-07-25 Thread Keller, Jacob
Dear Crystallographers, It seems to be a usual assumption that anomalous scattering is essentially angularly-independent, e.g.: http://pd.chem.ucl.ac.uk/pdnn/diff1/anomscat.htm But why the can't we see anomalous-only spots at e.g. 1 Ang resolution in a 2 Ang data set? This actually has some r

Dear James, It would seem to me that an important issue is also: do get all information out of our diffraction data? By integrating the Bragg peaks we usually neglect the diffuse scattering that could potentially contain additional (dynamic) structural information. This can be cloudy diffuse sc
