| 0 | (3/2+) | 8.0 ms 4 % β- = 100 % β-n = 47 6 % β-2n = 13 3 | Mean square radius=1.42 fm2 14 (2006Kh08 in Si(33Na,X) reaction at E=33.79 and 38.79 MeV/nucleon, also measured energy- integrated cross sections. E(level): Mean square radius=1.42 fm2 14 (2006Kh08 in Si(33Na,X) reaction at E=33.79 and 38.79 MeV/nucleon, also measured energy- integrated cross sections. Possible member of K|P=(3/2+) rotational band as predicted in shell model calculations (2011GaZZ). |
| 429 | (5/2+) | E(level): Possible member of K|P=(3/2+) rotational band as predicted in shell model calculations (2011GaZZ). | |
| 1117 | (7/2+) | For a possible 1117-keV transition to the g.s. branching ratio is calculated as 4.2% (2011GaZZ), too weak to be seen in the work of 2011GaZZ. E(level): Possible member of K|P=(3/2+) rotational band as predicted in shell model calculations (2011GaZZ). |

1972Kl04: first identification and production of 32Na nuclide in U(p,X) reaction at E=24 GeV, CERN-ISOLDE facility. Measured isotopic half-life. Later publications from the same laboratory dealing with spectroscopic measurements: 1978De39, 1984Gu19
Other papers for production and cross section data: 1979We10, 1991Or01, 1997Ha11, 1998NoZW (also 1998NoZZ,1999YoZW), 2002Ra16 (also 2004Co29)
Mass measurements: 2007Ju03, 1991Or01
Measurement of mean square radii using 33Na beam: 2006Kh08
33Ne is particle unstable thus does not decay by β- to 33Na. 34Ne possibly decays by delayed-neutron decay to 33Na but no details are known about this mode. The 35Ne nuclide which could possibly decay by delayed-two neutron decay to 33Na has not been identified.
This nuclide is of possible relevance to "island of inversion " near n=20.
