| Abstract: | In this work, the atomic structure of Ti III is calculated using two methods, the Thomas-Fermi–Dirac-Amaldi (TFDA) method using the AUTOSTRUCTURE (AS) atomic structure code and the pseudo-relativistic Hartree–Fock (HFR) method using the Cowan (CW) atomic structure code. We used the terms and levels generated by the 19 configurations: 3p6 3d2, 3dns (n = 4–7), 3dnp (n = 4–7), 3dnd (n = 4–7), 3d nf (n = 4–7), 3p6 4s2,3p6 4s4p. Our calculated values are compared with available experimental and theoretical results and new theoretical data of our own are obtained. |
