Constructor of the ImpactIonizationTransformFunc functor.
The transform is responsible for appropriately decreasing the kinetic energy of the colliding particle and assigning appropriate velocities to the two newly created particles. To this end the energy cost of ionization is passed to the constructor as well as the mass of the colliding species and the standard deviation of the ion velocity (normalized temperature).
- Parameters
-
| [in] | energy_cost | energy cost of ionization |
| [in] | mass1 | mass of the colliding species |
