General Comments:

Identification: 1971Ar32: 232Th(40Ar,X) E=290 MeV, measured fragment isotopic yield.

Later studies of production and decay studies of 33Si: 1972Go32, 1972Go09, 1973Go33, 1991Zh24, 1991Or01, 1995ReZZ, 2002Mo29

2006Kh08: Cross section measurement in Si(33Si,X) E=30-65 MeV/nucleon, deduced ’reduced strong absorption radius= 1.0200 fm2 15. The 33Si beam obtained from fragmentation of 48Ca beam with 181Ta target at GANIL facility.

1999Ai02: Cross section measurement in Si(33Si,X) E=38-80 MeV/ nucleon at NSCL facility. Deduced strong absorption radius

Mass measurement: 2009Kw02 (mass excess=-20514.30 70)

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

Q-value: Q(β-n)=-4259 16 (2003Au03, 2009AuZZ)
