The neutrons become much more compacted, but they do not merge into each other because neutron degeneracy pressure prevents any two neutrons from occupying the same state.
Electron degeneracy pressure is the mechanism which supposedly prevents the further collapse of white dwarfs.
Theory has it that, if a neutron star born after a supernova blast is too massive for neutron degeneracy pressure to keep it bouncy against the neutron star's own gravity, the quarks that composed the neutrons now can save the shriveling stellar-corpse from being squeezed out of existence.
Since degeneracy pressure doesn't need fuel it can, if left alone, support the star forever.
