General Comments:

42S identified and produced by 1975WiZG using 48Ca(α,10C) at E=110 MeV

Mass measurements: mass excess=-17637.9 27 (2009Ri12), -17700 130 (2000Sa21) (weighted average of -18060 330 (2000Sa21) and -17640 140 from another study quoted by 2000Sa21), 1991Zh24

42S produced by fragmentation of 48Ca beam (2009Ri12,2002Az02,1998WiZX, 1998WiZV); 64Ni(48Ca,X) E=60 MeV/nucleon (1995So03); Th(p,X) E=800 MeV (1991Zh24); 238U(40Ar,X) E=263 MeV (1979Au03); 9Be(48Ca,X) E=212 MeV (1979We10).

Cross-section measurements: 2006Kh08, 2006Ro34

Q-value: S(2n)=10943 5, S(2p)=37650 230, Q(β-n)=1600 70 (2012Wa38)
