Calculations of atomic structures and electron impact excitation cross sections of B-like Xe⁴⁹⁺

Atomic parameters of highly charged ions (HCI) are primely important for plasma control and diagnostics. A large amount of atomic data is needed to develop new spectral diagnostics for studying magnetic fusion plasma. Xenon, a rare gas, has been widely used in diagnosing tokamak fusion plasmas, for example, in ITER. The temperatures in these magnetic fusion devices can go up to 25 keV, producing all possible highly charged states of Xe ions, hence necessitating the atomic data for highly charged xenon ions. Recently, studies on calculating the atomic parameters of various HCIs of xenon have been reported. However, there is a scarcity of extensive results for boron-like Xe. In fact, the NIST ASD has no results for energies and transition lines for boron-like Xe. Motivated by the significance of atomic data of various ions of Xe in plasma physics, we aim to carry out an extended calculation to provide atomic parameters for boron-like Xe ions.
