Additional Level Data and Comments:
| E(level) | Jπ(level) | T1/2(level) | Comments |
| 0 | (3/2-,5/2-) | 11.3 ms 6 % β- = 100 % β-n = 52 46 % β-2n = ? | %β-n: from 1995ReZZ,2008ReZZ. Other: 52 11 (1999YoZW, preliminary). E(level): %β-n: from 1995ReZZ,2008ReZZ. Other: 52 11 (1999YoZW, preliminary). |
| E(level) | E(gamma) | Comments |
| 206+X | 206 | E(γ): From 2017Mo26. |
| 445+X | 445 | E(γ): weighted average of 443 7 (2017Mo26) and 446 5 (2011Ga15) |
| 619+X | 619 | E(γ): weighted average of 616 8 (2017Mo26) and 621 7 (2011Ga15) |
| 670+X | 670 | E(γ): From 2011Ga15, as this γ is not resolved from the 616γ in 2017Mo26, but its presence is indicated in the fit of the spectrum. 2017Mo26 states that the origin of the 670γ remains vague. |
Isotope discovery (2012Th10): Ta(48Ca,X) projectile fragmentation at GANIL (1989Gu03,1991Or01)
35Mg production:
2012Kw02: 35Mg produced by natNi(40Ar,X) at E(40Ar)=140 MeV/nucleon at NSCL. Measured fragmentation cross sections, parallel momentum transfers, and widths. Compared with empirical formula EPAX, and predictions from internuclear cascade and deep inelastic models using Monte Carlo ISABEL-GEMINI and DIT-GEMINI codes.
2011FuZZ: 35Mg produced by 9Be(48Ca,X) fragmentation at E(48Ca)=345 MeV/nucleon at RIKEN. Measured thick target fragmentation, deduced production cross sections, and compared with EPAX-2.15 systematics.
2007Ts09: Analyzed fragmentation σ of n-rich Na, Mg isotopes (including 35Mg) from 9Be,181Ta(48Ca,X). Used systematics based on average binding energy to extrapolate towards drip line, predicting σ for 40Mg and discussing 39Na. Compared different extrapolation models.
35Mg decay measurements:
2013StZY: 9Be(48Ca,X) at RIKEN. Measured T1/2.
1999YoZW: 9Be(48Ca,X) and 181Ta(48Ca,X) at RIKEN. Measured T1/2 and %β-n.
35Mg radius measurements:
2011Ka01: 35Mg produced by 9Be(48Ca,X) fragmentation at GSI. Measured interaction cross sections with C and CH2 targets at 900 MeV/nucleon. Deduced rms matter radii.
2006Kh08: 35Mg produced by 181Ta(48Ca,X) fragmentation at E(48Ca)=60.3 MeV/nucleon at GANIL. Measured energy-integrated reaction cross sections at 30-65 MeV/nucleon using a silicon telescope as both active target and detector. Deduced reduced strong absorption radii, isospin dependence, and possible halo structure or large deformation.
35Mg mass measurements: 2025Ly01, 2007Ju03, 2001Sa72, 2000Sa21, 1991Or01
Theoretical calculations (binding energies, deformation, quadrupole moments, radii, levels, J, π, mass, T1/2, etc): 2023Ra22, 2021Ka07, 2020Mi15, 2016Ba59, 2016Sa46, 2016Sh05, 2015Sh21, 2014Ga13, 2014Wa14, 2013Ch31, 2013Li39, 2013Sh05, 2012Fo27, 2012Ho19, 2007Ha53, 2006Zh19, 2005Ch71, 2004Kh16, 1996Re10, 1991Pa19, 1991Pa21.
The level scheme is based on that of 2011Ga15 and 2017Mo26.
Q-value: S(2n)=5576.0 76, Q(β-n)=10455.8 74, from mass excesses of 15529.5 71 for 35Mg measured by 2025Ly01; 4962.9 27 for 33Mg and -2997.6 21 for 34Al from 2021Wa16. Values from 2021Wa16: S(2n)=5470 270, Q(β-n)=10570 270
Q-value: S(2p)=45070 660 (syst) (2021Wa16)
