摘要: We employ molecular dynamics (MD) computer simulations to investigate ions in electron plasmas at strong coupling. observed this regime a stopping power of highly charged low velocities which scales with the charge like Z1.5. This clearly deviates from Z2 ln(const./Z) scaling conventional weak coupling theories and is connected strongly enhanced local density electrons around caused by trapping high Rydberg states due multi-particle collisions occurring For parameters corresponding less coupled situation an cooler we find moderate enhancement created under influence external magnetic field.
