“…46 Moreover, the present version of the Jain−Khare model (after ref 43) becomes more rigorous without any considerable success. In the preceding section, we have applied revisited JK formulation, after Pal et al, 42 for the evaluation of single-differential cross sections and the integral direct ionization cross sections for carbon dimer and trimer molecules.…”

“…Keeping in view that the electrons in the exit channel are indistinguishable, there is equal probability of transfer of maximum primary electron energy ( E – I i ) to the secondary electron; hence, limits of integration over ε in eqs and become 0 to ( E – I i ). Taking into account the same concept, Pal and co-workers − employed this revisited approach to calculate the partial single-differential cross sections (as a function of secondary/ejected electron energy at fixed impinging electron energies), double-differential cross sections (as a function of secondary/ejected electron energy and the scattering angle at fixed impinging electron energies), and the integral partial and total ionization cross sections (as a function of incident electron energies for various types of molecules varying from diatomic to polyatomic molecules including the Bückminster fullerenes). − …”

We describe the recent progress in the development of the semiempirical approach developed by Jain and Khare for the calculations of ionization cross sections for molecules by electron impact. Along with the state-of-the-art description of this approach, the emphasis will be on the evaluation of cross sections for a carbon dimer, C2, and trimer, C3. Single-differential ionization cross sections as a function of secondary or ejected electron energy and averaged secondary electron energy for C2 and C3 are calculated at fixed impinging electron energies of 100 and 200 eV. The integral ionization cross sections are also derived from ionization threshold to 2000 eV. Extensive comparisons of the presently evaluated direct ionization cross sections with the only available theoretical binary-encounter-dipole model calculations of Kim and Rudd, spherical-complex-optical-potential model calculations of Nagama and Antony, DM model calculations of Deutsch and Märk, and the calculations of Michelin et al. based on the combination of the Schwinger variational iterative method and distorted wave approximation revealed a satisfactory agreement. The present study also establishes the validity of the semiempirical approaches and so provides a solid foundation for further applications to the larger molecules.

“…In this work, we chose to use the ionization cross-section of dimethylamine ( at 30 eV), which also has a 9 Å 2 value at 70 eV. 69 Considering this, it is possible to demonstrate once again the time of ML completion for ethanol (20 minutes) and ethylamine (24 minutes). Table 4 reports the list of experiments performed.…”

In the present work, we assess the effectiveness of singly differential cross sections (SDCS) due to electron-impact ionization by invoking the binary-encounter-Bethe (BEB) model on various atomic and molecular targets. The computed results were compared with the experimental and theoretical data. A good agreement was observed between the present and the available results. This agreement improves as the incident energy of the projectile increases. The model can be applied to compute the SDCS for the ions produced due to the electron-impact dissociative ionization process and the average energy due to the secondary electrons. Both these quantities are of interest in plasma processing and radiation physics.
