Abstracts of Research Work:

1.       KLL dielectronic recombination process of He-like up to O-like xenon ions, Chin. Phys. B 21, 013402 (2012)

In this work, the KLL dielectronic recombination (DR)processes of the highly charged He-like to O-like xenon ions have been studied systematically by using a  DR  program, which is based on multi-configuration Dirac-Fock (MCDF) method. The KLL DR resonant energies and corresponding resonant strengths have been calculated, emphasizing the effect of the Breit interaction on DR strengths especially. The theoretical KLL DR spectra are obtained  and  compared with the latest experimental results in Shanghai electron beam ion trap (EBIT).

2.  Energy-crossing and its effect on lifetime of the 4s24p 2P3/2 level for highly charged Ga-Like ions, Chin. Phys. Lett. 29, 073102 (2012)

Multi-configuration Dirac-Fock method was employed to calculate the energy levels and transition probabilities for the electric dipole allowed (E1) and forbidden (M1, E2) lines for the 4s24p, 4s4p2 and 4s24d configurations of highly charged Ga-like ions from Z=68 to 95. The lifetimes of the 4s24p 2P3/2 level of the ground configuration have  also been derived, respectively. Based on our calculations, it is found that the energy level of the 4s24p 2P3/2 is higher than that of the 4s4p2 4P1/2 for the high-Z Ga-like ions with Z ≥ 74, so as to occur an energy-crossing at Z=74. The effect of the energy-crossing is important to the calculation of the 4s24p 2P3/2 level lifetime for Ga-like ions with Z ≥ 74.

3.       Theoretical study of the KLL dielectronic recombination for highly charged iodine ions,  Phys. Lett. A 372, 4913 (2008)

   With a developed program for calculation of dielectronic recombination (DR) process, which is based on multi-configuration Dirac–Fock (MCDF) method, the KLL DR processes of the highly charged helium-like to carbon-like iodine ions have been studied systematically. The contributions to doubly excited states from quantum electrodynamic (QED) and Breit effects have been discussed. The KLL DR resonant energies and corresponding resonant strengths have been calculated. The behavior of KLL resonant strengths with increasing Z are analyzed for He-like ions in particular. The theoretical DR spectra for each highly charged ion species are obtained in the KLL region. Comparison has been made between the present calculations and the latest experiments in Tokyo-EBIT.

4.  Relativity, electron correlation and QED effects in the 1s2s2 2S1/2 state of highly charged Li-like ions, J. Phys. B: At. Mol. Opt. Phys. 39, 3121 (2006)

   On the basis of a multiconfiguration Dirac–Fock method, a systematic study has been carried out for the decay process of the 1s2s2 2S1/2 state of Li-like ions. It is found that the decay properties of these states are quite different along the isoelectronic sequence: for low-Z ions up to Z = 30, the Auger decay channel is dominant; for medium-Z ions up to Z = 80, a two-electron one-photon radiative decay caused by a strong electron correlation becomes a competitive channel; and for very heavy ions about Z = 90, the magnetic dipole radiative decay becomes important too. In addition, the QED contributions to the excitation energy and the contributions from the Breit interaction to the Auger decay rates are stressed for heavy ions in particular.

5.  Theoretical investigation of decay process in a doubly excited 2s2 1S0 state of He-like ions, Chin. Phys. Lett. 23, 2059 (2006)

   In the framework of multi-configuration Dirac-Fock theory, a detailed calculation has been performed for the  decay rates and the energies of the doubly excited state 2s2 1S0 of He-like ions, of which atomic number Z ranges from 6 to 92. The 2s2 1S0 - 1s 2S1/2 Auger decay is predominant at low Z regime, whereas the 2s2 1S0-1s2p 1,3P1 two-electron one-photon transitions become quite important at moderate and high Z regime. For heavy ions with Z ≥ 72, the contribution of 2s2 1S0-1s2s 3S1 M1 transition is significant. The Breit interaction  considerably enhances the 2s2 1S0 - 1s 2S1/2 Auger rate at high Z regime.
