The two most prominent processes of ion-matter interaction are the energy loss and charge exchange, whereby the first depends on the charge state of the ion as determined by the latter. However, up to now there has existed no closed calculation of these two major processes. We herewith present, within an integrated approach, a Monte Carlo calculation which intrinsically entails target ionization/excitation, as well as charge exchange and projectile ionization/excitation on equal footing, especially extended to the situation of ion-solid interaction.
离子与物质相互作用的两个最显著过程是能量损失和电荷交换，其中前者取决于由后者所确定的离子电荷态。然而，到目前为止，尚未存在对这两个主要过程的封闭计算。在此，我们采用一种综合方法给出一种蒙特卡罗计算，该计算本质上同等考虑了靶的电离/激发、电荷交换以及入射粒子的电离/激发，尤其将其扩展到了离子 - 固体相互作用的情形。
