E(level): From a least-squares fit to γ-ray energies, except where noted.
Jπ(level): Based on intensity considerations and comparison to shell model calculations in 208Pb(36S,39Sγ) (2016Ch33), unless otherwise noted.

First identification of 39S nuclide by 1971Ar32.
Other measurements:
1971Ar32: 232Th(40Ar,X) E=290 MeV
1980Hi01: 39S produced in 40Ar(n,2p) reaction
1997Fo01: 208Pb(37Cl,X) E=230 MeV. Measured yield of 39S
1999Ai02: 39S beam produced by fragmentation of 55Mn beam at 50, 90 MeV/nucleon with a 9Be target. Measured energy- integrated cross sections; deduced strong absorption radii
2008Kl02: 39Cl(μ-,ν),40Cl(μ-,nν)
Other: 1975Ka38
Following γ rays have been assigned to this nuclide in different decays and reactions; but none has been assigned in a level scheme: 339.88 11, 398.61 14, 465.45 19, 904 7, 1126.2 7, 1524.6 7. Note that 398.61+1126.2=1524.8; from 40P β-n decay, 339.88γ and 398.61γ are in coin with 465.45γ, but not with each other; and 339.88+1126.2=1466.1 which is close to 1469 group seen in (13C,14O) reaction
Level scheme is from 2016Ch33 in 208Pb(36S,39Sγ).
Q-value: S(2n)=12410 50, S(2p)=31170 120 (2017Wa10)
