General Comments:

2007No13: |J0.1 mb and |J0.12 mb production cross sections were measured for 29Mg in 40Ar fragmentation reactions of 9Be(40Ar,X), E=90 MeV/nucleon, and 181Ta(40Ar,X), E=94 MeV/nucleon, respectively.

2006Kh08: 29Mg beam, 59.64 and 52.15 MeV/nucleon, bombarded a Si target, measured σ=2226 mb 334 and σ=2246 mb 85, respectively, for the Si(29Mg,x) reaction and a squared reduced absorption radius r02=1.18 fm2 4 is deduced and used to study the isospin dependence.

Q-value: Note: Current evaluation has used the following Q record 7613 11 3655 12 16903 15 -10968 46 2011AuZZ,2003Au03

Q-value: 2003Au03: Q(β-)=7596 14
