Electron impact total cross sections for Furan, Tetrahedrofuran and 2, 5-Dimethylefuran (0.1 eV -- 5000 eV)

Furan may serve as a prototype of a furanose-form building unit of biomolecules [1]. Electron interactions with tetrahydrofuran (THF), that links the phosphate groups in the DNA backbone, have been studied by both experimental and computational methods [2]. We have calculated various total cross sections for electron interactions with Furan, Tetrahedrofuran and an industrially relevant molecule 2, 5 -- Dimethylefuran. We have used R-matrix code [3] below 15 eV and Spherical Complex optical Potential (SCOP) and Complex Scattering Potential -- ionization contribution (CSP-ic) formalisms [4] beyond 15 eV.\\[4pt] [1] Szmytkowski et al.
