An efficient grid-based Langevin formulation is developed for treating electron-electron (e-e) and electron-ion collisions within a particle-in-cell plasma simulation code. The formulation is energy-and momentum-conserving. If the thermal part of the electron velocity distribution is reasonably clos

## Abstract In the kinetic theory a great variety of physical systems is investigated by means of Boltzmann‐like equations. This approach is used for neutral gases, neutron as well as radiation transport, plasmas etc. For many problems the knowledge of the properties of the collision operators is o
