Study of Electron Collisions with Isoprene, 1,2-Butadiene, and Their Isomers

Abstract

Isoprene, 1,2-butadiene, and their isomers play an important role in aerosols in the atmosphere, interstellar media, and extraterrestrial life. Since electrons are everywhere, studying how electrons interact with these molecules is an important part of studying such environments. To date, however, little investigation has been conducted in this area. Bearing this in mind, we conducted a thorough investigation to report the various electron scattering cross sections of isoprene, 1,2-butadiene, and their isomers. The methods used for this purpose are reliable within the limits of adopted model potentials. The optical potential method was used to get the total elastic and inelastic cross sections, while the complex scattering potential ionization contribution method was used to get the total ionization cross section from the inelastic contribution. The results from these approximations are pretty close to the results from earlier experiments and theories. Furthermore, most of these isomers are being explored for the first time. Besides, their isomeric effect is also discussed. A correlation between the cross sections of molecules is demonstrated, which can be used to predict cross sections of those molecules where previous data are not available.

Positron scattering from structurally related biomolecules

“…The spherical complex optical potential (SCOP) and complex scattering potential ionisation contribution (CSP-ic) methods have been extensively employed to calculate both electron [37][38][39][40][41][42][43] and positron [44][45][46][47] scattering cross sections for a wide range of molecules over a broad energy spectrum, generally from ionisation potential (IP) to 5 keV for electrons and 1 eV to 5 keV for positrons, respectively. Therefore, we will only briey reiterate the most important aspects of these approaches here.…”
