The Energy Level Structures And Oscillator Strengths Of1s²ns And1s²np States For As³⁰⁺ Ion

In this work, the As30+ion has been studied. In the introduction, the As element and the compound nature(including:chemical properties、harm、discovery and application etc.)、the history of the atomic and molecular physics and the high changed ions physics(including:the development history、preparation procedure in lab etc.).are simply introduced.Based on the FCPC method, the non-relativistic energies of1s2ns and1s2np states are calculated by using the square-integrated、analytic Slater-type wave function. In order to make calculation results to be more accurate, energy contributions of the core-correction and higher angular momentum partial wave are considered. On the foundation, the first-order perturbation correction is computed, in the meantime, QED effect and the higher-order relativistic correction are also estimated. The fine structure splitting of1s2np(2≤n≤9) states is given by counting expectation value operators of the spin-orbit and spin-other orbit interaction, QED contribution and the higher-order relativistic contribution are also calculated.After the total energy, the ionization energy、excited energy、transition energy and relevant wavelength are obtained. The quantum defects of Rydberg series are computed through the quantum defect theory. At the last, the length、speed and acceleration oscillator strength of1s2ns and1s2np states (2≤n≤9) are acquired, and calculation results are spread from the high excited states to the whole energy field.The experimental data of the lithium-like As30+ion in the high excited state is few. In the paper, energies of the high excited state are calculated by using semi-experience approach. The available energies are compared with semi-experience approach, both of the calculation results are nearly the same.
