Penetration of relativistic heavy ions through matter

Abstract New heavy-ion accelerators covering the relativistic and ultra-relativistic energy regime allow us to study atomic collisions with bare and few-electron projectiles. High-resolution magnetic spectrometers are used for precise stopping-power and energy-loss straggling measurements. Refined theories beyond the Born approximation have been developed and are confirmed by experiments. This paper summarizes the large progress in the understanding of relativistic heavy-ion penetration through matter, which has been achieved in the last few years.
