General Comments:

1985La03: First identification of 30Ne in Ta(40Ar,x) reaction at E=44 MeV/nucleon; measured fragment spectra vs mass.

1991Ro01: Ta(48Ca,X) at 55 MeV/nucleon. Measured projectile like fragment spectra.

1998NoZZ, 1998NoZW: Ta(40Ar,X) E=95 MeV/nucleon at RIKEN facility, measured isotopic half-life.

1999Re16, 1997Ta22 (also 2001Pe14,1999Dl01): 30Ne was produced by fragmentation of 36S beam at 2.8 GeV, time-of-flight and E-ΔE method for identification of fragments, four Ge detectors for γ-ray measurements; Ganil-Dubna collaboration; Measured isotopic half-life and delayed neutron branching.

Atomic excess mass measurement: 2007Ju03, 2000Sa21, 2001Sa72.

In 2006Kh08, 38.88 and 33.89 MeV/α beams of 30Ne impinged on a Si target, measured σ=2587 mb 219 and σ=2849 mb 399, respectively, for the Si(30Ne,x) reaction and a reduced strong absorption radius of <r02|>1.347 fm2 97 is deduced and used to study the isospin dependence.

Recent Structure Calculations: 2008Sc02, 2007Be54, 2006Ha07, 2006Ko02, 2006Sa29, 2006Zh05, 2005Ch71, 2005Sa63, 2005Ya28, 2004Ge02, 2004Ki12, 2004Kh16, 2004La24, 2004Lu10, 2004Va25, 2004Ya06, 2003Ki19, 2003Ro06, 2003St22.

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

Q-value: Δ(S(p))=800, Δ(Q(α))=600

Q-value: Q(β-)14700 600, S(n)=3000 600, S(p)=24000 800(syst), Q(α)=-15000 600(syst) (2003Au03)

Q-value: Q(β-n)=12370 570 (2003Au03)
