Abstract
Accurate nonrelativistic calculations of ionization energies and hyperfine structures for the 3{ital s} and the 3{ital p} states, and of the dipole transition 3{ital s}-3{ital p}, are presented for Na, using wave functions obtained in the coupled-cluster approach including single and double excitations (CCSD). Agreement with experimental results is at the percent level, corresponding to an error in the correlation contribution of approximately 5%. Certain three-body cluster contributions to the 3{ital s} ionization energy and the 3{ital s} hyperfine structure are evaluated and are found to account for the main part of the discrepancies between the values obtained from CCSD calculations and the experimental results.
