Query: Reduction of the Coulomb logarithm due to electron-neutral collisions   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.
