The coupled-cluster wave function factorizes to a very good approximation into a product of an intrinsic wave function and a Gaussian for the center-of-mass coordinate. The width of the Gaussian is in general not identical to the oscillator length of the underlying single-particle basis. The quality of the separation can be verified by a simple procedure.

Ab initio calculations of parity-violating electron scattering off $^{48}$Ca and $^{208}$Pb
Ab initio chiral EFT calculations of parity-violating asymmetries for 48Ca and 208Pb show mild tension with data and infer a neutron skin of 0.187(25)(18) fm for 208Pb.

Lattice simulation of nucleon distribution and shell closure in the proton-rich nucleus $^{22}$Si
Lattice chiral EFT simulations predict that 22Si is bound against two-proton emission and that its protons and neutrons fill the Z=14 and N=8 shells.
