Calculations of high lying energy resonances in the photoionization spectra of Ne+ using the screening constant by unit nuclear charge method

► Accurate energy positions of the 2s22p4 (1D2)ns,nd, 2s22p4(1S0) ns,nd and 2s2p5 (3P2)np Rydberg series of Ne+. ► Present results compared very well to theoretical and experimental literature values up to n=24. ► Quantum defect almost constant up to n=75. ► Presented data may be useful guideline for investigators focusing on the photoionization spectra of Ne+.
