“…4 shows the results obtained for the low energy spectra of 23 Na, calculated using the Hamiltonian parameters listed in the second row of Table 2, and the Hilbert space described above. This is compared with the experimental data [20], presented in the second column, (λ Ï , ” Ï ) (λ Îœ , ” Îœ ) (λ, ”) total (4,1)1/2 (4,2)0 (8,3)1/2 (9,1)1/2 (6,4)1/2 (7,2)1/2 (4,1)1/2 (5,0)1 (9,1)1/2,3/2 (7,2)1/2,3/2 (4,1)1/2 (2,3)1 (6,4)1/2,3/2 (7,2)1/2,3/2 (2,2)1/2 (4,2)0 (6,4)1/2 (7,2)1/2 (4,1)1/2 (3,1)0,1 (7,2)1/2,3/2 (2,2)1/2 (5,0)1 (7,2)1/2,3/2 (3,0)3/2 (4,2)0 (7,2)3/2 and with full shell model calculations performed by the Glasgow group [25] (third column). The ground state, as well as some excited states are well described using the quasi SU(3) truncation scheme.…”
