${}^{26}\mathrm{Mg}$ observables for the USDA and USDB Hamiltonians

Assignments are made between theory and experiment of corresponding levels in ${}^{26}\mathrm{Mg}$ levels based on energies, lifetimes, branching ratios, electron scattering form factors, and reduced electromagnetic transition strengths. Results based on the new $\mathit{sd}$-shell interactions USDA (universal $\mathit{sd}$-shell interaction A) and USDB (universal $\mathit{sd}$-shell interaction B), as well as the older USD interaction, are compared.

Figure 1

Comparison of experimental energies (left) vs the USDB theoretical energies (right) for positive parity states with angular momentum $J$, based on the associations made in Tables and . All theoretical levels up to 10 MeV are shown. Levels above 10 MeV correspond to $1^{+}$ levels shown in Fig. 6 and the lowest $8^{+}$ level.
