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.
