Extracting electron-ion differential scattering cross sections for partially aligned molecules by laser-induced rescattering photoelectron spectroscopy

Abstract

We extract large-angle elastic differential cross sections (DCSs) for electrons scattering from partially aligned O+2 and CO+2 molecules using rescattering photoelectrons generated by infrared laser pulses. The extracted DCSs are in good agreement with those calculated theoretically, demonstrating that accurate DCSs for electron-ion scattering can be extracted from the laser-induced rescattering spectra. © Published under licence by IOP Publishing Ltd.
