摘要

In this work,ionization potentials and quantum effects of 1s2np2p Rydberg states of lithium are calculated based on the calibrated quantum defect function.Energy levels and quantum defects for 1s2np2P bound states and their adjacent continuum states are calculated with the R-matrix theory,and then the quantum defect function of the 1s2np (n ≥ 7) channel is obtained,which varies smoothly with the energy based on the quantum defect theory.The accurate quantum defect of the 1s27p2P state derived from the experimental data is used to calibrate the original quantum defect function.The new function is used to calculate ionization potentials and quantum effects of 1s2np2P (n ≥ 7) Rydberg states.Present calculations are in agreement with recent experimental data in whole.
