Differential cross sections for e-LiF scattering

Differential cross sections are calculated for e-LiF scattering from 1 to 20 eV using a three-part hybrid method in which low-l partial waves are calculated using the multiple-scattering method, intermediate-l partial waves are calculated using the closed-form point dipole method and high-l waves are obtained using the first Born approximation. Good agreement between theory and experiment at 5.44 and 20 eV confirms the suitability of both the three-part hybrid approach and of the three separate approximations used therein. The differential cross section spectrum is dominated by dipole scattering at small angles, but clearly shows the influence of the molecular core at intermediate and large angles.
