No details are available about the decay of 32Ne to 32Na.
The existence of 33Ne nuclide, which can possibly decay to 32Na by neutron emission, has been searched (2007Ba71, 2002No11, 2002Lu09, 2002Lu19, 1997Sa14) but no events have been associated with this nuclide, estimated half-life < 180 ns, suggesting that 33Ne is unstable towards particle emission.
This nuclide is of possible relevance to "island of inversion " near n=20.
Q-value: S(2n)=5980 40, S(2p)=44900 500 (syst), Q(β-n)=13690 40 (2021Wa16)
