General Comments:

First identification of 40S nuclei by 1971Ar32 in 232Th(40Ar,X) at E=290 MeV

Mass measurements: 2009Ri12, 2007Ju03, 2000Sa21 (also 2001Sa72)

Other reactions:

2011FuZZ: 9Be(48Ca,X) E=345 MeV/nucleon. Measured thick target fragmentation. Deduced σ.

2006Kh08: Si(40S,X) E=30-65 MeV/nucleon. Measured energy-integrated reaction. Deduced radii (r20=1.282 fm2 25, isospin dependence.

2006Ro34: 2H(42S,X) E=99.8 MeV/nucleon. Measured production σ.

1999Ai02: Si(40S,X) E=38-80 MeV/nucleon. Measured mean energy-integrated cross sections, deduced strong absorption radii, r20=1.29 fm2 8

1997Fo01: 208Pb(37Cl,X) E=230 MeV. Measured yield

1991Zh24: Th(p,X) E=800 MeV. Measured fragment mass, charge ratio. Deduced mass excess

1986Du07: 9Be(40Ar,X) E= 60 MeV/nucleon. Measured βγ(t). Deduced T1/2, evidence for residuals production.

Q-value: S(2n)=12119 8, S(2p)=33250 70 (2012Wa38)
