General Comments:

1974Ja10: 32S(16O,3n) E=50-82 MeV. Surface-barrier counter telescope. α crude excitation curve indicated a maximum σ≈0.3 microbarn in the production of the activity near 75 MeV and a threshold below 65 MeV which is consistent with the 53-MeV threshold for (16O,3n) but not with the 74-MeV threshold for (16O,4n). The observed spectrum and T1/2 were not compatible with those of any other delayed-particle emitter compiled by 1973Ha77.

2007Do17: Ni(58Ni,X) E=74.5 MeV/nucleon. ALPHA-LISE3 fragment separator. Fragment identification by energy loss, residual energy and tof measurements using two micro-channel plate (MCP) detectors and Si detectors. Double-sided silicon-strip detectors (DSSSD) and a thick Si(Li) detector were used to detect implanted events, charged particles and β particles. γ’s detected by four Ge detectors. Coincidences measured between charged particles and γ’s.

Others: 1987Ki14 (12C(40Ca,X) E=292-520 MeV; activation) and 1985ReZW (calc(14N,x) E>140 MeV and calc(3He,x) E=110, 135 MeV; E(p), I(p), proton yields)

Q-value: Note: Current evaluation has used the following Q record

Q-value: Q(εp)=11.29 MeV 50

Q-value: Δ’=-18.94 MeV +50-60 (2004St05. Bare ions; isochronous mass measurement) compared to -18.97 MeV 50 (2003Au03. Syst).
