Hi Matthew, About the form factors : there is an active community doing "Quantum Crystallography" or charge density analysis with the IUCr. Some of them have been running a nice series of online lectures recently: https://qcrwebinar.chem.uw.edu.pl/ You can find many experts there, and there

Hi all I've been looking at atomic scattering factors recently, and in particular, the 11-coefficient parameterisation by Waasmaier and Kirfel [1]. In their paper, they give a parameterisation for O and O-, but in tables I can find online (eg libdiffpy/f0_WaasKirf.dat at master · diffpy/libdiffpy
