Quantum-defect studies of transitions in the diffuse spectral series of the potassium isoelectronic sequence

Abstract

Theoretical oscillator strengths are reported for transitions in the diffuse spectral series of some members of the potassium isoelectronic sequence (KI-CrVI). The calculations have been performed with the Quantum Defect Orbital (QDO) method. A core-polarization correction to the dipole transition moment has also been included in the formalism.
