用电荷转移模型讨论了入射能量为0.5 ~ 120kev /u的H原子穿过薄碳薄膜时的电荷交换性质。提出了一个用k空间中原子和固体电子波函数的重叠来解释固体中电荷态平衡的模型。在固体外部，靠近表面，电荷交换是通过碳表面和出射体之间的电子隧穿而发生的。
Charge exchange properties of H atoms passing through thin carbon foils at incident energies from 0.5 to 120 keV/u are discussed in the context of charge transfer models. A model is presented in which the charge state equilibrium in the solid is explained by the overlap of the atomic and the solid‐state electron wave functions in k space. Outside the solid, near the surface, charge exchange occurs by tunneling of electrons between the carbon surface and the exiting projectile.
