E(level): From a least-squares fit to the γ-ray energies. During the fit the uncertainty of 990.0γ depolating the 3461 keV level is increased from 0.5 to 1.0 to reduce the deviation less than 3|S.
Jπ(level): Based on 30Na β- decay feeding from 2+ g.s., except otherwise noted.
T1/2(level): From 31Na β-n decay, except otherwise noted.
M(γ): From (18O,2pγ) based on γ-ray transition character, except otherwise noted.

Atomic excess mass measurement: 2006Ga04
Nuclear effective root-mean-square (rms) radius measurement: 3.06 fm 2 and 3.08 fm 2, restricting size and diffuseness parameters, respectively (1998Su07,1997Su04).
Production cross sections |J50 μb and |J0.2 mb were measured in fragmentation of 9Be(40Ar,X): E=90A MeV and 94A MeV and 181Ta(40Ar,X): E=94 MeV/nucleon, respectively (2007No13).
In 2006Kh08, 55.77 and 48.73 MeV/α beams of 30Mg impinged on a Si target, measured σ=2370 mb 86 and σ=2342 mb 37, respectively, for the Si(30Mg,x) reaction and a reduced strong absorption radius of <r02|>1.215 fm2 18 is deduced and used to study the isospin dependence.
