The Level Of Fine Structure And Oscillator Strengths Of1s²nd And1s²nf States For As³⁰⁺ion

The As³⁰⁺ion has been studied in this paper.In introduction part,the chemical properties ofarsenic and arsenic compounds, physical properties, harm and application are simplyintroduced. History of the atomic and molecular physics and the high changed ions physicsare introduced too.This work is based on the method for FCPC. the non-relativistic energy of1s2nd （3≤n≤9）and1s2n’f stat（e4≤n’≤9）are calculated with the square-integrated、analytic Slater-type wavefunction。In order to make the data of calculation more accurate,the core-correction and higherenergy contributions are added to the calcualtion of energy. In this work, the first-orderperturbation correction,higher-order relativistic and the QED effect are considered. The levelof fine structure of1s2nd （3≤n≤9） and1s2n’f（4≤n’≤9） state are obtained with theexpectations of spin-spin orbit interaction and spin-other orbit interaction calculated in thiswork.After geting the total energy, excitation energy, the ionization energy, the transitionenergy and wavelength of the system are calculated.The quantum defects of Rydberg seriesare computed with the quantum defect theory. At the last,the length velocity and accelerationof transition oscillator strength are calculated., and the extrapolation to the whole energy fieldis predicted in this work.
