Theoretical Study On1s²nd-1s²n’f Transitions Of Zn²⁷⁺ion

First of all, the highly charged ions are simply introduced in this article, and then the zinc element and the application of the zinc element are illustrated. Secondly, the energy level and spectral property for the Is2nd and1s2n’f states of Zn27+ion are calculated and discussed.The non-relativistic energies are obtained by using variational method. In this process FCPC wave functions are determined. Relativistic effects (including correction to kinetic energy, Darwin term, electron-electron contact term, and orbit-orbit interaction) and mass polarization corrections are evaluated as the first-order perturbation corrections. The higher-order relativistic and quantum-electrodynamics (QED) correction are also included by introducing the effective nuclear charge, and then ionization potential, excitation energy, transition energy and wavelength are all obtained. Although the reference data of these Rydberg series is very seldom and notice that the fit is absolutely stunning. With the expectation value of spin-orbit and spin-other orbit interaction calculated, the fine structure splitting are determined and the results error is very small and much less than other theoretical data. The quantum defects of these Rydberg series are determined according to the single-channel quantum defect theory. Lastly, the oscillator strength for the1s2nd-1s2n’f transitions of Zn27+ion are calculated. It is clearly that the results under different forms are in accord with one another, and then we get the dipole transition oscillator strengths which are an initial state to all the final excited states of the Rydberg series. So the behaviors of any highly excited states can be reliably predicted.
