Abstract
Accurate resonance energies and quantum defects for various Rydberg series originating from the 3s23p5 (2P°3/2) ground and 3s23p5 (2P°3/2) metastable states of K III ions are reported up to n = 30. Theoretical photoionization is performed in the framework of the screening constant per unit nuclear charge (SCUNC) method. The SCUNC predictions, believed to be the first calculations, agree very well with the only available advanced light source (ALS) measurements. Some of the overlap peaks in the ALS measurements are clearly identified via the present SCUNC calculations. The present work demonstrates the strength of the SCUNC formalism to assist experimenters in the analysis of measurements from synchrotron radiation. New data are tabulated for n = 15–30.
