The collective nonideal effects on the symmetric resonant charge transfer process in the intermediate velocity region are investigated in partially ionized hydrogen plasmas. The effective pseudopotential model taking into account the plasma screening and collective effects is applied to describe the interaction potential in nonideal plasmas. The electron transfer probability and cross section are obtained as functions of the energies of the symmetric and antisymmetric stationary states, nonideality plasma parameter, Debye length, and collision velocity. The results show that the collective effects enhance the symmetric resonant electron transfer probability as well as the electron transfer cross section in nonideal plasmas. It is also found that the collective effects on the symmetric resonant charge transfer process are more significant than the screening effects in nonideal plasmas.
