Scientific paper

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 3s(2 ) 3p(2) , 3s(2) 3p nd (n= 3,4,5), 3s(2) 3p ns (n=4,5) and 3s(2) 3p 4p configurations of the Si-like ion SIII in the LS-coupling scheme. The present oscillator strengths, which are of considerable interest in astrophysics, are compared with other theoretical results and laboratory measurements, although the latter are extremely scarce for fine-structure transitions.
