General Comments:

1979Sy01: 35Al produced and identified in 12C(40Ar,X) reaction.

1988Mu08: fragmentation of 48Ca at 45 MeV/nucleon by 181Ta(86Kr,X) reaction. Measured T1/2.

1989Le16: fragmentation of 48Ca at 45 and 55 MeV/nucleon by 181Ta(48Ca,X) reaction at the French National Facility GANIL. Measured T1/2 and delayed neutron emission probabilities.

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. See also 2008ReZZ communication

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

2001Nu01 (also 2002Nu02): 35Al produced at the ISOLDE facility at CERN in fragmentation with 1.0 GeV proton beam on a uranium carbide target. Measured Eγ, Eγ, γγ, βγ-coin, T1/2 and delayed-neutron branches. Deduced levels, Jπ, log ft for 35Si.

2005Ti11: fragmentation of 36S beam at 78 MeV/nucleon at GANIL. Measured β-delayed Eγ, T1/2 and delayed neutron emission probability. Deduced levels, Jπ, log ft for 35Si. (conference paper)

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. (conference paper)

2006FuZX: He(35Al,X), E=40 MeV/nucleon, measured Eγ, Iγ. One γ ray at 760.1 keV 21 reported in in-beam γ-ray spectrum, but no level scheme was proposed.

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, and widths. Comparison with empirical formula EPAX, and predictions from internuclear cascade and deep inelastic models using Monte Carlo ISABEL-GEMINI and DIT-GEMINI computer codes.

2012Zh06: 9Be(40Ar,X),E=57 MeV/nucleon, measured particle spectra, energy loss, time of flight, fragment yields, momentum distributions, cross sections; deduced fragment excitation energies, mass yield ratios at RIBLL and HIRFL facilities.

2015Mo17: 9Be(40Ar,X),E=95 MeV/nucleon, measured time-of-flight, energy loss and angular distribution of fragments using RIKEN Projectile Fragment Separator; Analyzed transverse momentum distributions for fragments; deduced formulation for the width of transverse momentum distribution.

2017Ha23: E=69.2 MeV/nucleon 40Ar beam was produced at the Heavy Ion Research Facility in Lanzhou (HIRFL). Target was 182.6 mg/cm2 thick 9Be. Fragments were identified based on energy loss, time-of-flight, and magnetic rigidity on an event-by-event basis, and implanted into a 1500-μm-thick double-sided Si strip detector (DSSD) between two plastic scintillators. Measured half-life of 35Al decay from implant-β decay curve. Comparisons with previous measurements.

Mass measurements: 2017Ga20, 2007Ju03, 1991Or01, 1991Zh24, 1987Gi05

Nuclear structure theory calculations for binding energies, deformation, quadrupole moments, radii, levels, Jπ, mass, T1/2, etc.: eight 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.

Q-value: Q(β-n)=11662 16, S(2n)=7869 10, S(2p)=38580 450 (2017Wa10). Evaluators deduce Q((β-2n)=4150 6 from mass values in 2017Wa10
