ResumoWe report calculations of accurate high lying resonance energies of the [3s32p(D5/2°2)3]nd and [3s32p(P3/2°2)3]nd Rydberg series originating from the ground 3s32p4P23 and from the 3s32p4P1,03 metastable states of Cl+ along with the [3s32p(P1/2°2)3]nd Rydberg series originating from the 3s32p4S01 metastable state of the Cl+ ion. Calculations are performed using the Screening Constant by Unit Nuclear Charge (SCUNC) method up to n = 40. The results obtained are compared with the existing Dirac – Coulomb R-matrix (DCR) calculations (McLaughlin, 2017) and Advanced Light Source (ALS) measurements (Hernández et al., 2015). Analysis of the present results is achieved in the framework of the standard quantum-defect theory and of the SCUNC-procedure based on the calculation of the effective charge. It is shown that the SCUNC-method agree very well the ALS measurements up to n = 13. New high lying accurate resonance energies (n = 14–40) are tabulated as benchmarked data for the atomic physics community in connection with the modeling of plasma and astrophysical systems.
