Electron scattering cross sections from anthracene over a broad energy range (0.00001–10,000 eV)

We report a computational investigation of electron scattering by anthracene (C14H10) in the gas phase. Integral and differential cross sections have been calculated by employing two distinct ab-initio quantum scattering methods: the symmetry adapted–single centre expansion method (ePOLYSCAT) and a screening corrected form of the independent atom model (IAM–SCAR) at low and high energies, respectively. After a detailed evaluation of the current results, we present a complete set of integral scattering cross sections from 0.00001 to 10,000 eV.

► Integral and differential electron cross sections were calculated for anthracene. ► At intermediate energies, ePOLYSCAT and IAM–SCAR methods are smoothly joined. ► A complete set of integral ECS, ICS and TCS from 0.00001 to 10,000 eV is given. ► Computed elastic angular distributions are satisfactorily compared with experiments.
