Abstract

Energy levels, oscillator strengths and transition probabilities for dipole-allowed transitions among levels of the terms belonging to the 3s23p2, 3s3p3, 3s23p3d, 3s23p4s, 3s23p4p, 3s23p4d, and 3s23p5s configurations of S in are calculated using the multiconfiguration Hartree-Fock (MCHF) method. The relativistic effects are incorporated through mass, Darwin, spin-orbit, and spin-other-orbit operators in the Breit-Pauli Hamiltonian in our calculations of the energy levels, oscillator strengths, transition probabilities and lifetimes for all fine-structure levels belonging to these configurations. The present results are compared with other available calculations and measurements. These data provide a powerful tool to study the composition, structure, dynamics and energetics of atmospheres of the Io-torus-Jupiter system and other astrophysical objects.
