Impacts of a power-law non-thermal electron tail on the ionization and recombination rates [PDF]

, 2001
We have investigated the effects of a non-thermal electron population on the ionization and recombination rates. The considered electron distribution is defined as a Maxwellian function below a break energy E_b and as a power-law function of index alpha ...
