Atomic structure of the doubly ionized titanium Ti III ion
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.

In this work we studied the Stark widths of Ar IV ion which are important for modelling atmosphere of some particular stars. Using semiclassical perturbation and modified semi-empirical approach,…
Using semiclassical perturbation approach in impact approximation, Stark shifts for singly charged argon (Ar II) spectral lines have been calculated. Energy levels and oscillator strengths needed…
