Abstract
The fine-structure energy levels and lifetimes are calculated for the lowest 218 levels of the 2s(2)2p(5), 2s2p(6), 2s(2)2p(4)3s, 2s(2)2p(4)3p, 2s(2)2p(4)3d, 2s2p(5)3s, 2s2p(5)3p, 2s2p(5)3d, 2p(6)3s, 2p(6)3p, 2p(6)3d, 2s(2)2p(4)4s, 2s(2)2p(4)4p, 2s(2)2p(4)4d, 2s2p(5)4s, 2s2p(5)4p, and 2s2p(5)4d configurations in Sc XIII using the general-purpose relativistic atomic structure package (GRASP). The atomic data of the electric dipole (E1), electric quadrupole (E2), magnetic dipole (M1), and magnetic quadrupole (M2) transitions from the levels of 2s(2)2p(5), 2s2p(6), 2s(2)2p(4)3s, 2s(2)2p(4)3p, 2s(2)2p(4)3d, 2s2p(5)3s, 2s2p(5)3p, 2s2p(5)3d, 2p(6)3s, 2p(6)3p, and 2p(6)3d configurations to the levels of the 2s(2)2p(5) and 2s2p(6) configurations are presented. The GRASP results are compared with the other calculations and measurements.
