Abstract—

The energy loss straggling for fast ions is simulated using the Monte Carlo method in the case of large and small transferred momenta. The interval of applicability of the Bohr approximation is determined for frequently used solid targets. The asymmetry in the distribution of ion energy losses is related to the influence of large transferred momenta and is observed in wide intervals of ion energy and target thicknesses.

薄靶穿透后离子能散逸的描述

摘要—

在传递动量较大和较小的情况下，使用蒙特卡罗方法模拟了快速离子的能量散逸。对于常用的固体目标，确定玻尔近似的适用间隔。离子能量损失分布的不对称性与较大的传输动量的影响有关，并在较宽的离子能量和目标厚度范围内观察到。
