Oscillator strengths for lines of astrophysical interest in Rh II⋆
Aims. This work reports oscillator strengths for transitions of astrophysical interest in singly ionized rhodium. Methods. Seventeen radiative lifetimes in Rh have been measured with the time-resolved laser-induced fluorescence technique and combined with theoretical branching fractions calculated using a relativistic Hartree-Fock model including core-polarization effects to obtain oscillator s...
متن کاملPhotodissociation of small carbonaceous molecules of astrophysical interest
Astronomical observations have shown that small carbonaceous molecules can persist in interstellar clouds exposed to intense ultraviolet radiation. Current astrochemical models lack quantitative information on photodissociation rates in order to interpret these data. We here present ab initio multi-reference configurationinteraction calculations of the vertical excitation energies, transition d...
متن کاملOscillator strengths for transitions of astrophysical importance in SIII
Relativistic Quantum Defect Orbital (RQDO) calculations, with and without explict account for core-valence correlation, have been performed on dipole-allowed transitions between the levels belonging to the 3s2 3p2, 3s2 3p nd (n = 3, 4, 5), 3s2 3p ns (n = 4, 5) and 3s2 3p 4p configurations of the Si-like ion SIII in the LS-coupling scheme. The present oscillator strengths, which are of considera...
متن کاملCALCULATIONS OF OSCILLATOR STRENGTHS AND LIFETIMES OF CuI, AgI AND AuI USING COULOMB APPROXIMATION
Oscillator strengths and lifetimes of all energy levels of CuI, Agl and AuI were calculated using the Coulomb approximation (for The first time), and then compared with available data
متن کاملAstrophysical line diagnosis requires nonlinear dynamical atomic modeling.
Line intensities and oscillator strengths for the controversial 3C and 3D astrophysically relevant lines in neonlike Fe(16+) ions are calculated. A large-scale configuration-interaction calculation of oscillator strengths is performed with the inclusion of higher-order electron-correlation effects, suggesting that these contributions cannot explain existing discrepancies between theory and expe...
