相对论带电粒子在吸收介质中的辐射能量损失
Radiative energy loss of relativistic charged particles in absorptive media
摘要：
我们确定了相对论电荷穿越色散介质的能量损失谱。介质中的偏振和吸收效应通过复折射率进行建模。我们发现，由于吸收机制，频谱振幅呈指数衰减。考虑到多次散射对电荷轨迹的影响，我们确认了在以前的工作中得到的结果。
英文摘要：
We determine the energy loss spectrum per time-interval of a relativistic charge traversing a dispersive medium. Polarization and absorption effects in the medium are modelled via a complex index of refraction. We find that the spectrum amplitude becomes exponentially damped due to absorption mechanisms. Taking explicitly the effect of multiple scatterings on the charge trajectory into account, we confirm results obtained in a previous work.
