Theoretical Calculation On The Transition Energies And Oscillator Strengths For1s²ns-1s²np Of Br³²⁺Ion

The status and development of Atomic Physics are introduced in this work, which alsoilluminated the properties and the importance of the highly charged ions in the related fields.The non-relativistic energies of the lithium-like ions of Br32+are obtained by applying the FullCore Plus Correllation Method. In order to get the theoretical data of high-precision, theRelativistic Effects and Mass Polarization Corrections are calculated as the first-orderperturbation corrections. At the same time, the effect of quantum electrodynamics(QED) andhigh order relativistic effect to the system are considered.In addition, the ionization potentials, transition energies, transition wavelengthes and theexcitation energies of the system are computed. According to the calculation of expectationvalues of spin-orbit interaction and spin-other-orbit interaction operators, the fine structuressplitting of the lithium-like ions of Br32+are acquired.On the basis of the Theory of quantum defect, the article calculated the quantum defectof two Rydberg series of1s2ns and1s2np for the lithium-like ions of Br32+, and the theoreticalpredictions of the higher excited states are obtained.The work also calculated the dipole oscillator strength for the1s2ns-1s2n’p(2≤n≤9，3≤n’≤9) transitions of the lithium-like ions of Br32+.If the initial state is determined,anypossible oscillator strength from initial state to other discrete states permitted can becalculated with the single channel quantum defect theory (QDT). At last, the oscillatorstrength can be extrapolated to continuous states, the calculation of the oscillator strengthdensity from the initial state are gained.
