A Method to Obtain Time Dependent Electron Eigenstate Populations with Electron Collisions and an Arbitrary Radiation Field.

Abstract

A computer module has been written which solves the time dependent electron eigenstate popuation problem under the influence of electron collisions as well as spontaneous and induced radiative transitions to bound or free states. Degree of ionization is automatically included. Electron velocity distribution must be represented by a Maxwellian. Radiation is represented as photon groups, called features, with flat central regions and Lorentz like tails. Photon features can be superimposed, so that a rather general line and continuum combination can be represented. Check out examples discussed in the final section indicate that photoionization may be a more important phenomenon at high altitude than is generally appreciated. Keywords: Radiative Collisional Transitions; Eigenstate Population; Opacity.
