Relativistic calculations of photoionization cross sections of Ne-like Sc XII using the Breit-Pauli R-matrix method in close-coupling and LS-coupling approximation and fully relativistic distorted-wave method are reported. In present work, the relativistic distorted-wave method is employed to calculate the fine-structure energy levels and radial functions, and the Breit-Pauli R-matrix method is employed to calculate the photoionizaton cross sections. In present work, we calculated the photoionization cross sections of Sc XII for ejection of 2p or 2s electron from the ground 2s22p61S0 in jj-coupling and obtained the energy levels and widths of 2s22p5ns 3P1, 2s22p5nd 1P1 (n = 21−30), 2s2p6np 3P1 and 2s2p6np 1P1 (n = 5−15). The photoionization cross sections of Sc XII for ejection of 2p electron from the excited state 1s22s22p53s3,1P have been calculated in LS-coupling and obtained the energy levels and widths of 2s2p6ns 1,3S and 2s2p6nd 1,3D (n = 5−15).
