Binding energy and B(E2;41+→21+) calculations for nuclei with A=20

Binding energy of the ground state, energy levels and the reduced probability for E2 transitions for O, F, Ne, Na and Mg nuclei with mass number A=20 and nucleon numbers between 8 and 12 have been calculated through shell model calculations using the shell model code OXBASH for Windows by employing the usdapn interaction for neutron and proton particles orbits in sd-shell. The binding energies calculations are in good agreement with experimental data. The predicted low-lying levels (energies, spins and parities) and the reduced probability for E2 transitions results are reasonably consistent with the available experimental data.
