General Comments:

Other studies:

Measurement of yields in fragmentation reactions: 2012Kw02, 2012Zh06, 2007No13

Measured one neutron removal cross section to be 71 mb 8 (2010Ro23) on Be.

24Ne on 208Pb, E=7.9 MeV/nucleon (2007Be66)

In 2006Kh08, cross section=2141 mb 137 at magnetic rigidity (βρ)=2.753 Tm, E=60.63 MeV/u and cross section=2097 mb 44 at βρ=2.575 Tm, E=53.06 MeV/u for Si(24Ne,X) and related reduced strong absorption radius <r02>=1.179 fm2 24 was measured. The later one was used to study the isospin dependence of the reduced strong absorption radius.

Q-value: S(2n)=14069.6 5, S(2p)=29810 60 (2021Wa16)

E(level): From a least-squares fit to γ-ray energies for levels with depopulating gammas, using equal weight for γ without uncertainty. In absence of depopulating γ, level energies are from particle data set.

Jπ(level): Additional spin assignments, not adopted, are suggested in reaction datasets.

T1/2(level): From (t,pγ - DSAM), except where otherwise noted.

I(γ): Relative photon branching from each level.
