The effect of radiation-resonant interactions (RRI) between ion-acoustic waves and electrons is treated, including the beam-plasma instability in the presence of ion-acoustic turbulence. It is shown that the change in the subthermal part of the electron distribution function due to the production of fast particles on account of the RRI of ion-acoustic waves and plasma electrons gives rise to a reduction in the growth rate for Langmuir waves, which in turn can lead to stabilization of the beam instability. Criteria for stabilization of the beam instability are found. Conditions are obtained under which the electron energy increases due to RRI faster than the electron energy increases due to the nonlinear interaction of resonant and nonresonant waves with the beam and faster than the rate at which the electron energy changes due to the quasilinear interaction. 12 refs.
