Relativistic quantum defect orbital calculations of oscillator strengths in neutral chlorine

Abstract

The Relativistic Quantum Defect Orbital (RQDO) method without and with explicit inclusion of core polarization hasbeenappliedtothestudyofoscillatorstrengthsofnestruc- ture transitions in neutral chlorine, some of which are important in interstellar chemistry. The resulting oscillator strengths are analyzed in terms of other theoretical results and some avail- able experimental data. For the 3p 4 ( 3 P)4f 3p 4 ( 3 P)5g lines we supply the only available results at the moment.
