Transition Rates for 3s3p² ⁴P–3s3p4s ⁴P° Transitions in Al i Froese Fischer, Charlotte; Babb, James F.

Abstract

Fully relativistic calculations have been performed for two multiplets, 3s3p² ⁴P and 3s3p4s ⁴P°, in Al i. Wave functions were obtained for all levels of these multiplets using the grasp programs. Reported are the E1 transitions rates for all transitions between levels of these multiplets. Transition energies and transition rates are compared with observed values and other theory. Our calculated transition rates are smaller by about 10% than observed rates, reducing a large discrepancy between earlier calculations and experiments.
