固体靶次级电子发射的Monte Carlo研究：经典二元碰撞模型中球对称性与动量守恒
A Monte Carlo investigation of secondary electron emission from solid targets: spherical symmetry versus momentum conservation within the classical binary collision model
摘要：
一个Monte Carlo方案中描述的次级电子产生已被纳入。由于费米海激发的次级电子的初始位置被假定为发生非弹性碰撞的位置，而次级电子的极角和方位角可以用两种不同的方法来计算。第一种假设次级电子的随机方向，对应于慢次级电子应该以球对称产生的想法。这种方法违反了动量守恒。计算次级电子的极角和方位角的第二种方法考虑了经典二元碰撞模型中的动量守恒规则。本文的目的是比较这两种不同的方法来确定固体靶发射的次级电子的能量分布的结果。
英文摘要：
A Monte Carlo scheme is described where the secondary electron generation has been incorporated. The initial position of a secondary electron due to Fermi sea excitation is assumed to be where the inelastic collision took place, while the polar and azimuth angles of secondary electrons can be calculated in two different ways. The first one assumes a random direction of the secondary electrons, corresponding to the idea that slow secondary electrons should be generated with spherical symmetry. Such an approach violates momentum conservation. The second way of calculating the polar and azimuth angles of the secondary electrons takes into account the momentum conservation rules within the classical binary collision model. The aim of this paper is to compare the results of these two different approaches for the determination of the energy distribution of the secondary electrons emitted by solid targets.
