论文摘要
使用线性等离子体响应形式主义，计算出对通过理想电子气体移动的测试电子的摩擦力（停止功率）。这使我们能够阐明有效的库仑对数如何受电子碰撞的影响。与Hagelaar，Donko和Dyatko的最新调查一致[Phys。莱特牧师。 {\ bf 123}，025004（2019）]我们观察到，由于电子中性碰撞，有效的库仑对数大大降低，并且与高度碰撞的限制中的碰撞频率成反比。
The frictional force (stopping power) acting on a test electron moving through the ideal electron gas is calculated taking into account electron-neutral atom collisions using the linear plasma response formalism. This allows us to elucidate how the effective Coulomb logarithm is affected by electron-neutral collisions. In agreement with a recent investigation by Hagelaar, Donko, and Dyatko [Phys. Rev. Lett. {\bf 123}, 025004 (2019)] we observe that the effective Coulomb logarithm decreases considerably due to electron-neutral collisions and becomes inversely proportional to the collision frequency in the highly collisional limit.
