Abstract

The low-energy spectrum of ions reflected from the surface of a solid is calculated theoretically and by means of the computer simulation method. The theory is based on numerical solution of the transport equation by of the method of discrete streams; and computer simulation, on the model of binary collisions and local inelastic energy losses. It is shown that, for small energies of reflected ions, their energy distributions are described by the universal formula containing the only constant. The value of this constant varies weakly when passing from the hard-core potential to the Coulomb one.

反射离子的能量分布与原子势类型的关系

摘要

从固体表面反射的离子的低能谱在理论上并通过计算机模拟方法进行计算。该理论基于离散流方法对输运方程的数值求解。和计算机模拟，对二元碰撞和局部非弹性能量损失的模型。结果表明，对于反射离子的小能量，其能量分布由包含唯一常数的通用公式描述。从硬核电势到库仑电势时，该常数的值变化很小。
