DOI: 10.1063/5.0162336
Abstract: Fast electron scattering on plasma ions due to stimulated Bremsstrahlung is investigated and modeled. Comparison with Coulomb scattering suggests that stimulated Bremsstrahlung scattering can be dominant in low-density, radiation-driven plasmas, provided that the radiation spectrum… read more here.

DOI: 10.1063/5.0281660
Abstract: This work extends the previously developed mean force emission theory to describe electron–ion plasmas. Results are compared to molecular dynamics simulations. The main extensions are to account for the attractive nature of electron–ion interactions and… read more here.

Abstract: ABSTRACT Concretes are used for shielding in nuclear power plants. Beta radiation is emitted during the nuclear reactions. This beta radiation interacts with the concrete and results in secondary radiation such as bremsstrahlung. Shielding parameters… read more here.
