| In this work, the theoretical research on properties of the Rydberg states1s2nl(l=d,f)forBr32+ion is based on the full core plus correlation(FCPC) method. Firstly, the non-relativisticenergy for Br32+ion is calculated, in which the correction of core and the higher angularmomentum contributions to the non-relativistic energy are considered. Relativistic correctionincluding one-order relativistic, mass-polarization effect, quantum-electro dynamic (QED)contribution and higher-order relativistic contribution is added to obtain accurate results. Thenthe high-precision relativistic energy for Br32+ion is obtained. Secondly, the fine structure andquantum defect of Rydberg states are calculated with the wavefunction and energy. At the last,we study the oscillator strength of1s2nd (3≤n≤9)-1s2n’f (4≤n’≤9) transitions, and relativisticlength oscillator strength is calculated with the relativistic energy. With the quantum defecttheory, the oscillator strength can be extrapolated to the entire energy region. By the abovework, we finish the calculations of the Br32+ions and enrich the data which can provide thereference for theoretical and experimental research. |
