Study on energy levels of atom neon

In this article, energy levels of atom neon are studied systematically using the weakest bound electron potential model theory. Under the concept of spectrum-level-like series, energy levels are expressed as a function of principal quantum number. In the calculation, the perturbations among different series are included. The results of 1s22s22p5(2P3/2o)ns, 1s22s22p5(2P3/2o)np and 1s22s22p5(2P3/2o)nd series are given and compared with experimental values. Deviations between the present results and experimental values are generally less than 1 cm−1.
