平板和弯曲晶体中的非相干韧致辐射

Incoherent bremsstrahlung in flat and bent crystal

N. F. Shul'ga, V. V. Syshchenko, A. I. Tarnovsky

摘要:

晶体中相对论性电子的韧致辐射截面分为相干和非相干部分(非相干部分是由于晶体中原子的热运动引起的)。虽然晶体中的非相干辐射的光谱与非晶介质中的光谱相似,但由于电子通量在晶体中的重新分布,非相干辐射强度可以表现出对晶体取向的实质依赖性。在本文中,我们应用我们的方法的非相干韧致辐射模拟早期开发的解释最近在美因茨微波MAMI获得的一些实验结果。

英文摘要:

The bremsstrahlung cross section for relativistic electrons in a crystal is split into the sum of coherent and incoherent parts (the last is due to a thermal motion of atoms in the crystal). Although the spectrum of incoherent radiation in crystal is similar to one in amorphous medium, the incoherent radiation intensity could demonstrate substantial dependence on the crystal orientation due to the electrons' flux redistribution in the crystal. In the present paper we apply our method of the incoherent bremsstrahlung simulation developed earlier to interpretation of some recent experimental results obtained at the Mainz Microtron MAMI.
