E(level): From a least-squares fit to γ-ray energies where available and the rest from (t,p), unless otherwise noted.
E(γ): Values from (18O,16Oγ) seem systematically higher as compared to those in β- decay, (t,pγ) and 160Gd(36S,38Sγ): 4 keV for 1296γ, 5 keV for 1538γ

  1292.02  1292.0E(γ): weighted average of 1292.3 4 from 38P β- decay (0.64 s) and 1291.9 2 from (t,pγ). Others: 1296.2 4 from (18O,16Oγ), 1292 4 from (48Ca,Xγ), 1286 19 from Coulomb excitation.

  3725.3   900E(γ): from (18O,16Oγ) with value adjusted by 3 keV lower than the original value=903 1 since all values in that dataset are systematically lower than values in other studies.
  4990.2  3698.0E(γ): from 38P β- decay

General Comments:

First identification of 38S nuclide is by 1958Ne10, according to the 2012Th10 compilation of isotope discovery.
Other reactions:
1994De17: 40Ar(e,e’2p) E=14.5 GeV; measured secondary protons.
1999Ai02: strong absorption radius deduced from measured cross section
2005Ol04: 208Pb(38S,Xγ): γ rays at 1292 and 1513 reported using CLARA Ge detector array and PRISMA magnetic spectrometer. (Preliminary results).
