Pauli exclusion holds neutron stars and atomic nuclei apart. ie. much denser than atomic contact.

Even with the clouds overlapping, I think it's mostly electromagnetic. They are too sparse for exclusion to be significant.

To get any deeper, we would need someone who understands the source and mechanism of exclusion.

The Pauli exclusion principle applies to all fermions, including both electrons and nucleons. The PEP for nucleons is what keeps neutron stars from collapsing (normally). But the PEP for electrons keeps electron clouds from overlapping (much).
