In the present work, a modification of a previously developed electron cascade model
is presented. More than one electronic state is incorporated in the model as well as various
loss processes. Thus, new inelastic process such as photo ionization a
nd electron impact
ionization of the electronic excited state of the argon atom are considered. Moreover, loss
processes which may act to deplete the number of electron such as electron diffusion; three
body recombination and dissociate recombination are taken into account. All these
processes are incorporated into the time-dependent Boltzmann equation which is solved
numerically simultaneously with set of rate equations for both the electron energy
distribution function (EEDF) and the excited state population respectively.
