表面等离子体激发下Vavilov-Cherenkov效应中的辐射反冲
Radiative Recoil in the Vavilov-Cherenkov Effect with Excitation of Surface Plasmons
摘要：
类似于均匀空间中的Vavilov-Cherenkov效应的效应将在具有良好反射的轻金属-电介质边界的空间中观察到。主要的区别在于，一个能量为几十电子伏的电子会激发出一个电子伏的量子。这将成为可能，因为与均匀空间的波的速度相比，表面等离子体速度非常小。在激发的等离子体激元之间存在一个等离子体激元，其线性动量与电子的两倍初始动量一样高。
英文摘要：
An effect that is an analogue to the Vavilov-Cherenkov effect in a uniform space would be observed in a space with a boundary of well reflecting light metal-dielectric. The main difference is in that quanta of some electron volt would be excited by an electron of energy of some tens of electron volts. This would become possible because the surface plasmon velocity is very small as compared with the velocity of waves of a uniform space. Beetwen excited plasmons there is a plasmon with a linear momentum as high as the doubled initial momentum of the electron.
