General Comments:

1989Gu03, 1991Or01: first identification of 35Mg nuclide in 181Ta(48Ca,X) reaction at 55 MeV/nucleon at the French National Facility GANIL.

1995ReZZ: Nuclei of interest produced by 232Th(p,X) at 800 MeV in the Time-of-flight spectrometer at the LAMPF accelerator. Measured half-life, delayed neutron-emission probability

1999YoZW: Fragmentation of 48Ca beam at 70 MeV/nucleon by 9Be and 181Ta targets at RIKEN. Measured half-life and delayed-neutron branches.

2006Kh08: Secondary beams produced by fragmentation of 48Ca beam at 60.3 MeV/nucleon by 181Ta targets at GANIL. Used a silicon telescope as both reaction target and detection system. Measured energy-integrated reaction cross-sections. Deduced radii, isospin dependence.

2007Ts09: Fragmentation of 48Ca beam at 64 MeV/nucleon by 9Be and at 140 MeV/nucleon by 181Ta targets at the National Superconducting Cyclotron Laboratory (NSCL), analyzed cross sections and binding energies.

2011Ka01: E=900 MeV/nucleon secondary 35Mg beam from Be(48Ca,X) primary reaction. Target=CH2. Fragment separator at GSI facility. Measured interaction cross sections by detecting unreacted Mg particles by Bρ-ΔE-tof method. Deduced matter radius by Glauber model analysis. Comparison with HF and RMF predictions.

2012Kw02: 9Be,Ni,181Ta(40Ar,X),E=140 MeV/nucleon, measured fission fragment spectra by energy loss from time-of-flight measurements, average isobaric velocities, parallel momentum transfers, widths, fragment s. Comparison with empirical formula EPAX, and predictions from internuclear cascade and deep inelastic models using Monte Carlo ISABEL-GEMINI and DIT-GEMINI computer codes.

2013StZY: 35Mg 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 35Mg 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 35Mg.

Mass measurements: 2007Ju03, 2001Sa72, 2000Sa21, 1991Or01

Nuclear structure theory calculations for binding energies, deformation, quadrupole moments, radii, levels, Jπ, mass, T1/2, etc.: 18 references extracted from the NSR database are listed as document records in the ENSDF dataset.

The 36Na isotope is expected to decay by neutron emission to to 35Mg, but particle instability of 36Na is proposed only from its non-observation.

This nuclide is of possible relevance to "island of inversion " near n=20.

The level scheme from 2011Ga15 is tentative

Q-value: Q(β-n)=10570 270, S(2n)=5470 270, S(2p)=44940 650 (syst) (2017Wa10). Evaluators deduce Q(β-2n)=7995 270, Q(β-3n)=2525 270 from mass values in 2017Wa10
