摘要: The nuclear plus interference scattering (NIS) effect on the stopping power of hot dense beryllium (Be) plasma for multi-MeV protons is theoretically investigated by using generalized Brown-Preston-Singleton (BPS) model, in which a NIS term taken into account. analytical formula detailedly derived. By this formula, density and temperature dependence numerically studied, results show that becomes more important with increasing or density. Different from cases traveling through deuterium-tritium plasmas, Be plasma, prominent oscillation valley structure observed when proton's energy close to E_{p}=7MeV. Furthermore, penetration distance remarkably reduced considered.
