Theoretical Results

Energies, wavelengths, lifetimes, oscillator strengths, electric dipole (E1), electric quadrupole (E2), magnetic dipole (M1), and magnetic quadrupole (M2) transition rates among the 42 fine structure levels belonging to the 3s23p4, 3s23p33d, and 3s3p5 configurations for S-like Fe and S-like ions with 41 ≤ Z ≤ 49 are calculated using the fully relativistic multiconfiguration Dirac–Fock (MCDF) method. In the calculations, contributions from correlations within the n = 6 complex, Breit interaction, and quantum electrodynamics effects are included. Detailed comparisons are made between the present results and the available experimental and other theoretical data. We found that our calculated energy levels generally agree within ≤0.5% with the experimentally compiled results, and the transition rates agree within ≤12% with other theoretical results for a majority of the transitions. These accurate theoretical data should be beneficial in fusion plasma research and astrophysical applications.

Variational calculations are carried out with a multiconfiguration-interaction wave function to obtain the relativistic energies of the 1s2 2 ln l 1 S (m)(n =2–6, m1–5) states for the beryllium isoelectronic sequence (Z =4–10). Relativistic corrections and the mass polarization effects are evaluated with the first-order perturbation theory. The identifications of the energy levels for 1s2 2 ln l 1 S (m)(n =2–6, m1–5) states in the Be-like ions are reported. The oscillator strengths, transition rates and wavelengths are also calculated. The calculated results are compared with other theoretical and experimental data in the literature.

The reduced electric quadrupole transition rates have been calculated for the states of the negative parity bands in [Formula: see text]Cd nuclei using semiclassical model (SCM). The calculated transition rates are found to be decreasing with increasing spin for the states above [Formula: see text] and the dynamic moment of inertia [Formula: see text] of the higher spin states are found to be almost constant. The calculated B(E2) values show better agreement with the experimental B(E2) values for [Formula: see text]Cd. The results for both [Formula: see text]Cd and [Formula: see text]Cd nuclei show a very rapidly increasing value of the [Formula: see text] ratio with increasing spin, suggesting the antimagnetic rotational character of the states lying above the spins [Formula: see text] and [Formula: see text], respectively.
