Secondary electron energy and angle dependent differential cross sections for the production of cations SiHn+ (n=0–3), H2+ and H+ resulting from dissociative ionization of SiH4by electron collision have been evaluated at fixed incident electron energies of 100 and 200 eV. The semiempirical formulation of Jain and Khare which requires the oscillator strength data as a major input has been employed. In the absence of experimental data for differential cross sections, the corresponding derived integral partial and total ionization cross sections in the energy range varying from ionization threshold to 1000 eV revealed a satisfactory agreement with the available experimental and theoretical data. We have also evaluated the ionization rate coefficients on the basis of calculated partial ionization cross sections and Maxwell-Boltzmann energy distributions.

Due to abundant applications of ionization in various fields of applied sciences, it’s desirable to calculate absolute ionization cross sections of various atoms or molecules. In this literature, we have calculated the absolute direct and dissociative ionization cross sections of the oxygen molecule from threshold energy to 10,000 eV by using revisited Jain-Khare semi-empirical approach. In this literature, the total direct and absolute ionization cross section data have compared with easily available experimental and/or theoretical data. The present results give a better account for the ionization cross sections up to higher incident electron energies.

Several crossed-beam experiments were performed to acquire information concerning collisions of low-impact-energy electrons with ground-state or laser-excited sodium atoms prepared in 32P3/2, F = 3 (MF = +3 or −3) polarized states. Results of these experiments are the azimuthal asymmetry of the differential cross sections between two polarized states in the elastic electron collision (3P → 3P) at selected scattering angles, absolute differential cross sections for elastic, inelastic, and superelastic scattering obtained with no normalization procedure involved, and total ionization cross sections in the threshold energy range.

This review is devoted to a discussion of laboratory measurements of ionization, fluorescence, and photodetachment. The review is limited to molecules of aeronomic interest but excludes atoms. The section on photodetachment includes only work which has appeared since 1964. Current data are presented on photoionization cross sections, dissociative ionization cross sections, cross sections for the excitation of particular states of ions, relative vibrational excitation probabilities, photodetachment cross sections, angular distributions of electrons from photoionization, and dissociative excitation of neutral molecules. Some suggestions are made for further work.
