标题： Radiation of the atomic chains exited by a channeling particle

摘要： 原子链在被沟道粒子激发时的辐射基本性质被考虑。 使用一个非常简单的二维晶体晶格模型，我们表明，这种辐射的主要部分是在沟道粒子在晶面之间振荡的频率上产生的，该频率由于多普勒效应而发生了偏移。 由于由单个原子产生的场的相干性，振荡原子链的辐射角分布强烈地集中在沟道粒子的速度方向上。 显示英文摘要

摘要： Basic properties of radiation of the atomic chains excited by a channeling particle are considered. Using a very simple two-dimensional model of a crystal lattice we have shown that the main part of this radiation is generated on the frequency of oscillations of a channeling particle between the crystal planes, shifted by the Doppler effect. Angular distribution of the radiation of the chain of oscillating atoms is sharply peaked in the direction of the velocity of channeling particle because of coherence of the fields, produced by individual atoms.
