Electron correlation effects of the highly-doubly-excited resonances for He-like ions

The hyperspherical method is used to study the electron correlation energy，radiative transition rate and Auger transition rate of the highly-doubly-excited states of He-like oxygen.All these doubly-excited Rydberg states are designated by quantum numbers K，T，A.The results show that properties such as the energy，radiative and Auger transition rate regularly change along with the quantum numbers K，T，A.
