General Comments:

2021Bh12: Inferred indirectly 29Na(n,γ) reaction cross sections through Coulomb dissociation of 30Na at incident projectile energy of 430 MeV/nucleon on a 208Pb target using the FRS-LAND setup at GSI.

Nuclear effective root-mean-square (rms) radius measurement: 3.10 fm 3 and 3.13 fm 4, restricting size and diffuseness parameters, respectively (1998Su07,1997Su04).

2007No13: Production cross sections |J0.1 mb measured in fragmentation of 9Be(40Ar,X), E=90α MeV.

2012Zh06: Production cross sections |J0.016 mb and |J0.018 mb were measured in fragmentation of 9Be(40Ar,X) and 181Ta(40Ar,X), E=57 MeV/nucleon, respectively.

In 2006Kh08, 46.97 and 41.00 MeV/α beams of 30Na impinged on a Si target, measured σ=2363 mb 28 and σ=2402 mb 29, respectively, for the Si(30Na,x) reaction and a reduced strong absorption radius of <r02>=1.222 fm2 10 is deduced and used to study the isospin dependence.

Mass measurement: 2006Ga04, 2002To12, 2001Lu17.

Q-value: S(2n)=6680 11, S(2p)=3.951×104 12, Q(β-n)=11016 5 (2021Wa16)
