    Abstract
  • Using the Debye shielding model, the effects of plasma shielding on the dielectronic recombination processes of the H-like helium ions are investigated. It is found that plasma shielding causes a remarkable change in the Auger decay rate of the doubly excited 2p2 3P2 state. As a result, the dielectronic recombination cross sections from the doubly excited 2p2 3P2 state increases with the decreasing Debye shielding length.
