相对论粒子与晶面原子核的非相干散射
Relativistic particle incoherent scattering by the nuclei of crystal plane atoms
摘要：
本文提出了一个描述经典运动相对论性粒子与晶面核非相干散射的自洽理论，它不需要任何唯象参数。本文应用量子力学的基本概念，导出了粒子轨道单位长度上的均方非相干散射角的基本紧致公式。后者是用来实现的影响，晶体原子分布的不均匀性到库仑散射模拟，而不会显着延长的模拟时间。该理论基本上重新考虑了带正电的粒子从低核密度区域退散的性质，这在晶体波动器和设想的短生命粒子的特定电磁动量的测量中都是必不可少的。
英文摘要：
A consistent theory, which describes the incoherent scattering of classically moving relativistic particles by the nuclei of crystal planes without any phenomenological parameter is presented. The basic notions of quantum mechanics are applied to introduce a fundamental compact formula for the mean square incoherent scattering angle per unit length of particle trajectory. The latter is used to implement the effects of the crystal atom distribution inhomogeneity into the Coulomb scattering simulations without noticeable elongation of the simulation time. The theory essentially reconsiders the nature of positively charged particle dechanneling from the low nuclear density regions, being essential in both the crystal undulators and envisaged measurements of the specific electromagnetic momenta of short living particles.
