Electron-driven processes for furan, tetrahydrofuran and 2, 5-dimethylfuran

Abstract

ABSTRACTWe present the study of electron-induced processes for biomolecules, furan (C4H4O) and tetrahydrofuran (C4H8O) as well as an industrial relevant molecule 2, 5-dimethylfuran (C6H8O) through various total cross sections for impact energies from threshold to 5 keV. We have employed spherical complex optical potential to calculate total cross sections QT and total elastic cross sections Qel. Since these molecules are complex molecules, we have used the group additivity rule which incorporates molecular properties as well as geometry of the target to evaluate these cross sections. Dependence of QT and Qel on number of electrons and correlation of dipole polarisability (α) and ionisation potential (I) with peak of total ionisation cross sections Qion is studied and important inferences are noted. The present results for these applied molecules are compared with previous data wherever available. This is the maiden attempt to report Qel and QT for 2, 5-dimethylfuran.
