    Opis:
    The theoretical lifetimes for singly ionized beryllium (Be II) have been calculated using the weakest bound electron potential model theory and the quantum defect orbital theory under the assumption of the LS coupling scheme. In the calculations, many states are considered. Some lifetime values for highly excited levels have been obtained using these methods. The lifetimes presented in this work have been compared with the early theoretical calculations and measurements presented in the literature. A good agreement with the results in the literature has been obtained.

    Opis:
    Electric dipole oscillator strengths have been computed for transitions between both multiplet and individual lines in the Li(II) ion. The weakest bound electron potential model theory has been used. We have employed both numerical Coulomb approximation wave functions and numerical non-relativistic Hartree-Fock wave functions in the determination of expectation values of radii. The necessary energy values have been taken from experimental ionization energies. The oscillator strengths calculated with parameters obtained by using the two different wave functions have been compared not only to each other but also to other data taken from literature. A good agreement with results in literature has been obtained.

    Opis:
    We have calculated the spectroscopic data of the odd series nd [1/2]1 (3 ≤ n ≤ 9) of neutral argon atom relative to the ground level 3P⁶ ¹S₀ using a fully relativistic approach based on the Dirac equation. This series is one of three intermediate Rydberg series that converge to the first limit of ionization. The energy levels of this series are predicted. The obtained energy levels results are judged by comparing them with the experimental ones available in the literature. Within the uncertainty in the theoretical results, the agreement between our results and the experimental ones was found to be reasonable. Based on this agreement, the oscillator strengths f_{ij}, the radiative transition rates A_{ij}, the Landé g-factor, the magnetic dipole moment and the electric quadrupole hyperfine constants for the levels in question are calculated. The obtained results of f_{ij}, A_{ij}, and Landé g-factor are compared with the theoretical and experimental results published by other researchers where available as well as those published by NIST. Within the uncertainty in our results, a good agreement is found. Moreover, the studied levels are situated near and under the first limit of ionization where autoionization effects take place.

    Using the relativistic Hartree-Fock method developed by Cowan, we calculated the electric dipole (E1) transition parameters such as the wavelengths, the weighted oscillator strengths, and the transition probabilities (or rates) for doubly ionized lutetium (Lu III, Z=71). We compared the results with available calculations and experiments in literature. A discussion of these calculations for Lu III in this study has also been made in view of the relativistic Hartree-Fock method.

    We have reported the energies and radiative lifetimes of levels for doubly ionized xenon (Xe III) and radon (Rn III). The calculations have been performed using the general-purpose relativistic atomic structure package based on fully relativistic multiconfiguration Dirac-Fock method. We have compared the results obtained from this work for (Xe III) with previous works in available literature. For (Rn III), there is no data except a few energy levels. Hence, we have presented new values on the energy levels of (Rn III).

    Opis:
    Main properties of multiply charged molecular ions (energetics, structure, stability, lifetime and fragmentation dynamics) are relevant to know and to model the behavior of gaseous plasmas, planetary ionospheres, and astrophysical environments. Experimental measurements of the kinetic energy released of fragment ions produced by the Coulomb explosion of molecular dications (doubly charged molecular species) originating by double photoionization of CO₂ molecules, are reported and discussed. The kinetic energy released, as a function of the UV photon energy in the range of 34-50 eV, is extracted from the electron-ion-ion coincidence spectra recorded by using tunable synchrotron radiation coupled with ion imaging techniques at the GasPhase beam line of ELETTRA Synchrotron Light Laboratory Trieste, Italy. This kind of experiment allows assessing the probability of escape for simple ionic species in the ionosphere of Mars and Titan. The kinetic energy released, measured in the case of O⁺ and CO⁺ fragment ions, are ranging between 1.0-5.0 and 0.4-3.0 eV, respectively. These values are large enough to allow such ionic species in participating in the atmospheric escape from Mars (only O⁺ ions) and Titan (both O⁺ and CO⁺ ions) into space. In the case of Mars, we suggest a possible rationalization for the observed behavior of the O⁺ and CO₂²⁺ ion density profiles by Viking 1 lander and Mariner 6 spacecraft.
