摘要

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 2p~2 ~3P_2 state.As a result,the dielectronic recombination cross sections from the doubly excited 2p~2 ~3p_2 state increases with the decreasing Debye shielding length.
