General Comments:

1979We10: identification and production of 34Mg in 9Be(48Ca,X) reaction at 212 MeV/nucleon.

Later papers for decay studies of 34Mg nuclide: 1984La13, 1984Gu19

Mass measurements: 2007Ju03 (Penning-trap method), 2001Sa72 and 2001Sa21, 1991Or01 and 1991Zh24

2007No13: 9Be(40Ar,X) E=100 MeV/nucleon, RIKEN, measured production σ and momentum distribution

Cross section and strong absorption radius measurement in Si(34Mg,X) reaction at 43.43 MeV/nucleon: 2006Kh08.

2011Ka01: E=900 MeV/nucleon secondary 34Mg beam from Be(48Ca,X) primary reaction. Target=CH2. Fragment separator at GSI facility. Measured interaction cross sections by detecting unreacted Mg particles by Bρ-ΔE-tof method. Deduced matter radius by Glauber model analysis. Comparison with HF and RMF predictions.

Structure calculations: 2012Li11, 2011Hi18, 2009No01, 2008Yo08, 2006Zh05, 2005Ro10, 2004Ot02, 2001Ca49

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

Q-value: Q(β-n)=8926 113, S(2n)=6671 92, S(2p)=43016 511 (2011AuZZ). S(2p) is from systematics.

Q-value: Values in 2003Au03: Q(β-)=11740 260, S(n)=4160 230, S(p)=23370 910, Q(α)=-16720 620, Q(β-n)=9270 240, S(2n)=6380 230; S(2p)=43050 830 (syst)
