2007Ka18, 2005Ue01 (also 2007Ue02): E(⁴⁰Ar)=95 MeV beam produced using RIKEN accelerator. Spin polarized beam of ³²Al obtained by fragmentation of 95-MeV ⁴⁰Ar beam and using RIPS separator. Static quadrupole moment and magnetic moment of ³²Al g.s. determined by β-NMR method. Also 2007Ka68 from the same group

2006Kh08: Cross section measurement in Si(³²Al,X) E=30-65 MeV/nucleon, deduced ’reduced’ strong absorption radius= 1.23 fm² 3. The ³²Al beam obtained from fragmentation of ⁴⁸Ca beam with ¹⁸¹Ta target at GANIL facility.

1999Ai02: Cross section measurement in Si(³²Al,X) E=38-80 MeV/ nucleon at NSCL facility. Deduced strong absorption radius

Others:

1991Or01, 1987Gi05: Ta(⁴⁸Ca,X) E=55 MeV/nucleon, deduced mass excess

1986Vi09 (also 1987VaZS): ²³²Th(p,X) E=800 MeV, measured mass to charge spectra, deduced mass excess. Measured mass by time-of-flight isochronous mass spectrometer

Nuclear structure calculations: 2004Kh16, 1994Po05

The ³²Al nuclide is relevant to structure of nuclides in the "island of inversion ".

Q-value: Note: Current evaluation has used the following Q record 13020 90 4180 90 15160 90 -12500 90 2011AuZZ

Q-value: S(p)=15130 90 in 2003Au03, Q(β^-), S(n) and Q(α) are same as in 2011AuZZ
