摘要

The present study is devoted to the investigation of stimulated Raman backscattering of an intense, circularly polarized electromagnetic wave in magnetized electron-positron-ion plasma. The nonlinear dispersion relation as well as the growth rate of instability is achieved. The effects of external magnetic field, fraction of electron-positron pairs, pump frequency and also the kind of polarization on the growth rate is studied. It is shown that an admixture of e-p pairs to the ion-electron plasma modifies the behavior of plasma with respect to the external magnetic field.
