Abstract: | We have calculated the spectrum and polarization of the bremsstrahlung hard X-ray radiation produced by nonrelativistic electrons
that are accelerated during a solar flare. The distribution function of accelerated electrons is taken from the self-consistent
solution of the kinetic equation allowing for Coulomb collisions and an electric field of reverse current in plasma. The computed
polarization of the hard X-ray polarization is shown to be appreciably lower than the value given by simplified thick-target
models without considering the reverse current. |
