1983La12 (also 1984La03): 35Na produced and identified in Ir(p,X) reaction at 10 GeV in the CERN-ISOLDE facility. α 4πi-geometry liquid scintillator (4 l useful volume) associated with a thin plastic detector of the same geometry for detecting neutrons. Measured βn-coincidence and T1/2. Deduced evidence for 35Na.
2002LuZT: measured yield of 35Na in Ta(48Ca,X) E=59.8 MeV/nucleon fragmentation reaction
2013StZY: 35Na activity was produced in 9Be(48Ca,X) at E(48Ca)=345 MeV/nucleon from the RIBF-RIKEN facility. Fragments were separated using BigRIPS and ZeroDegree spectrometers on the basis of Bρ-ΔE-Bρ and tof measurements with position-sensitive detectors. Separated ions of 35Na were implanted into CAITEN segmented detector for recoils and β detection. The γ radiation was measured by DALI2 array of NaI(Tl) detectors and three Ge clover detectors. Measured half-life of the decay of 35Na.
Nuclear structure theory calculations for binding energies, deformation, quadrupole moments, radii, levels, Jπ, mass, T1/2, etc.: 13 references extracted from the NSR database are listed as document records in the ENSDF dataset.
This nuclide is of possible relevance to "island of inversion " near n=20.
β- or delayed-neutron decaying precursor nuclides 35Ne, 36Ne or 37Ne have not been experimentally identified.
Q-value: Estimated uncertainties: ΔQ(β-)=720, ΔS(n)=300, ΔS(p)=840, ΔQ(α)=870 (2017Wa10)
Q-value: Q(β-n)=21840 670, S(2n)=1690 810 (syst,2017Wa10). S(2p)=50400 (theory, 1997Mo25). From mass values in 2017Wa10, evaluators deduce Q(β-2n)=17120 770, Q(β-3n)=14845 770, Q(β-4n)=9070 770, Q(β-5n)=6760 770
