Opis:
We have calculated relativistic energies, Landé factors, and lifetimes for some excited levels outside the core [Xe] in neutral ytterbium (Yb I, Z=70) using two configuration interaction methods (multiconfiguration Hartree-Fock method within the framework of Breit-Pauli relativistic corrections developed by Fischer, and Cowan's relativistic Hartree-Fock method). Results obtained have been compared with other calculations and experiments.

We report calculations of wavelengths, oscillator strengths, and transition probabilities (or rates) for electric dipole (E1) transitions in doubly ionized cerium (Ce III, Z=58), using the relativistic Hartree-Fock method developed by Cowan. Comparisons are made with the previously reported available calculations and experiments in literature.

Opis:
By applying AUTOSTRUCTURE code, the energies and transitions for allowed (E1) and forbidden (E2, M1, and M2) lines for low-lying configurations in magnesium-like tungsten $(W^{62+})$ are studied. The electron correlation and relativistic effects are included in computations. Good agreement between our results and available other results are found. The data for E2, M1 and M2 besides some E1 transitions for low-lying levels are presented for the first time.

Opis:
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.

Opis:
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).

We have calculated the energies of some low-lying levels ($6d7s^2,$ $6d^2 7s,$ $6d7s7p$ and $6d^27p$) and electric dipole transition parameters (wavelengths, oscillator strengths and transition probabilities) between them for neutral actinium (Z=89). In the calculations, the correlation and relativistic effects are considered by multiconfiguration Hartree-Fock method within the framework Breit-Pauli Hamiltonian. The results obtained are compared with the available experimental and theoretical works in the literature.

Moreover, the results obtained were compared with other calculations and experiments.

In calculations, the Breit interaction and quantum electrodynamic effects have been included as perturbations. The calculated values for energy levels including valence and core-valence correlation have been compared with other available experimental and theoretical values in literature. Our transition results can provide useful data for, in particular, experimental works in future.

Opis:
The properties of resonant two-electron pairs are examined in three-dimensional simple cubic extended Hubbard tUW model, in s- and d- symmetry channels, in the limit of empty lattice. Lattice Green function technique is applied to calculate the scattering amplitude by means of matrix for any energy in the band on ΓR line within the Brillouin zone. The analysis shows the persistence of resonant states even for Coulomb interactions so weak that the equation for the resonant states is not formally fulfilled. The difference in behavior of resonances controlled by on-site and intersite Coulomb interactions is found. The ranges of applicability of approximate formula for the actual position of resonant peak and its width are shown.

Opis:
Precise values for electric dipole moments of isolated acetone and acetic acid molecules were determined from the Stark effect measurements made on lowest J rotational transitions at conditions of supersonic expansion. The new results are $μ_{tot} =μ_b$ =2.9345(22) D for acetone from measurements on the $1_{11}$← $1_{01}$ transition, and $μ_a$ =0.8631(8), $μ_b$ =1.4345(11), $μ_{tot}$ =1.6741(10) D for acetic acid, from measurements on $1_{11}$ ← $0_{00}$ and $1_{01}$ ← $0_{00}$ transitions. A comparison with previous determinations and with results of quantum chemical calculations is presented.
