Raman scattering in a plasma in the presence of a relativistic electron beam, which is expected for ICF experiments, is investigated through kinetic theory of plasmas. The effects of beam density, laser wavelength, laser intensity, and Lorentz factor of beam on growth rate of Raman scattering are investigated and findings are compared with those of two-stream instability. The increase of the density of electron beam increases the growth rates of Raman scattering and two-stream instability. Rise in Lorentz factor of electron beam has an adverse effect on the growth of two-stream instability which leads to the reduction of the growth rate of Raman scattering. The increase of laser intensity increases the growth rate of Raman scattering in this medium while increase of laser wavelength converses the process.
