| Abstract: | We report in this paper, energy resonances of the 2s22p4 (1D2)ns,nd, 2s22p4(1S0) ns,nd and 2s2p5 (3P2)np series originating from both 2s22p5 2P1/2 metastable and 2s22p5 2P3/2 ground state of Ne+. Calculations are performed using the Screening Constant by Unit Nuclear Charge (SCUNC) method and high lying states up to n=75 are investigated. The results obtained in this work agree very well with Advanced Light Source experiments on Ne+ (Covington et al., 2002). The analysis of the present results is achieved by calculating the effective charge number in the framework of the SCUNC formalism and by evaluating the quantum defect from the standard quantum defect expansion formula. Both effective nuclear charge and quantum defect are almost constants up to n=75. |
