Abstract The electron impact partial ionization cross sections (PICS) for isobutanol were calculated using variants of the binary encounter Bethe model (BEB). The modified BEB (m-BEB) model and the mass spectrum dependent (MSD) method are used to calculate the PICS of cationic fragments of isobutanol due to electron impact. In the absence of any other data for isobutanol, the present PICS is compared with the PICS data for other isomers of butanol.

Elucidating the significance of low-energy electrons in the rupture of DNA/RNA and the process involved in it is crucial in the field of radiation therapy. Capturing of the incident electron in one of the empty molecular orbitals and the formation of a temporary negative ion (TNI) is considered to be a stepping stone towards the lesion of DNA/RNA. This TNI formation manifests itself as a resonance peak in the cross-sections determined for the electron-molecule interaction.
