  journal={arXiv: Chemical Physics},
We have implemented a procedure that allows the use of non-spherical atomic form factors in a standard crystallographic X-Ray refinement. We outline the procedure for their use, alongside a mathematical justification of their viability.

Hirshfeld atom refinement based on projector augmented wave densities with periodic boundary conditions
Deriving the atomic form factors from Hirshfeld-partitioned periodic projector augmented wave calculations shows a great benefit for H-atom bond lengths and a smaller benefit for H-atom atomic

Coherent X‐Ray Scattering for the Hydrogen Atom in the Hydrogen Molecule
The x‐ray form factors for a bonded hydrogen in the hydrogen molecule have been calculated for a spherical approximation to the bonded atom. These factors may be better suited for the least‐squares
