Abstract
The need for a reliable and comprehensive database of cross-sections for many atomic and molecular species is immense due to its key role in R&D domains such as plasma modelling, bio-chemical processes, medicine and many other natural and technological environments. Elastic, momentum transfer and total cross-sections of butanol and pentanol isomers by the impact of 6–5000 eV electrons are presented in this work. The calculations were performed by employing the spherical complex optical potential formalism along with single-centre expansion and group additivity rule. The investigations into the presence of isomeric variations reveal that they are more pronounced at low and intermediate energies. Elastic, total cross-sections (with the exception of n-pentanol) and momentum transfer cross-sections for all pentanol isomers are reported here for the first time, to the best of our knowledge. Our momentum transfer cross-sections for butanol isomers are in very good agreement with the experimental and theoretical values available, and in reasonable consensus for other cross-sections.

There has been a heightened interest in the study of higher alcohols for their significant role in industrial applications and research
There is a pressing need for a reliable and comprehensive database of cross-sections for these species, as they play a key role in R&D domains such as plasma modelling [3], bio-chemical processes [4], health [5], environment [6], etc
In order to facilitate a complete dataset of cross-sections [9], we report the data for elastic (Qel), momentum transfer (Qmtcs) and total cross-sections (Qt) for butanol and pentanol isomers under the present theoretical study
Summary
There has been a heightened interest in the study of higher alcohols for their significant role in industrial applications and research Species such as butanol and pentanol are axial to the development of bio-fuels [1] and are the mainstay of all major proposed solutions to the looming world energy crisis. In order to facilitate a complete dataset of cross-sections [9], we report the data for elastic (Qel), momentum transfer (Qmtcs) and total cross-sections (Qt) for butanol and pentanol isomers under the present theoretical study This is in continuation to the theoretical calculations of total ionisation cross-sections (Qion) for the same species, reported in our earlier work [10]
