General Comments:

Mass measurements: 2003Bl17, 2009Kw02, 2009Sc09

Mass deduced from IMME analysis: 2010Ka30

Strong absorption radius measurement: 1999Ai02:

Theoretical nuclear structure calculations: consult Nuclear Science References database at www.nndc.bnl.gov/nsr/ for 65 primary references.

Q-value: S(2n)=15787.36 30, S(2p)=29772 3 (2017Wa10)

Q-value: Note that S(n)=9203.218 keV 5 deduced by 2001Pa15 from 31S(n,γ) is in disagreement with value from 2017Wa10, who had considered this measurement in their global AME analysis.
