Notes:
The angular dependence of Doppler profiles of atomic fluorescence produced in electron impact dissociation of molecules was simulated in consideration of the effect of the anisotropy of dissociation and the "polarization'' in magnetic sublevel. The asymmetry parameter b and the polarization of the electric vector of emission Jp are key parameters of Doppler profiles for the excited atom of known translational energy distribution. The difference of two Doppler profiles taken at 90° and 45°, which is denoted as angular difference Doppler profile, is shown to be useful to estimate these two key parameters.
