Abstract
In this paper, the calculated ionization potential by the R-matrix method is compared with that by the full-core-plus-correlation (FCPC) method, which can verify the accuracy of the wave function. The quantum defects of the Rydberg series of the 1s2nh states from Sc XIX to Zn XXVIII ions are calculated by the R-Matrix method. The quantum defect function of the 1s2nh channel is obtained by theoretical calculation with the R-Matrix method. The quantum defects and highly excitated energies of high Rydberg states of the 1s2nh states for lithium-like ions are calculated. Thus the reliable theoretical prediction of energies and quantum defects for the high Rydberg state of lithium-like ions is realized.
