Abstract
Oscillator strengths of the dipole-allowed fine-structure transitions in Si II between the terms belonging to the 3s2 nl (n = 3-10) and l = 0-3 configurations have been calculated in the LS-coupling scheme using the Relativistic Quantum Defect Orbital method, with and without accounting explicitly for the core-valence correlation. The present f-values are compared with other available results for this astrophysically important ion, and good agreement has been found.Keywords
