Is it not true that X-ray crystalography gives as distances between
scattering centers (atoms) and not sizes of atoms? To estimate sizes of
atoms one can assume that (in solids) they "essentially touch each
others."

The size of an atomic nucleus can be operationally defined in terms of
ranges of nuclear forces. Can the size of an atom be operationally
defined in the same way?
