Abstract

We present a method based on multiple-scattering to determine elastic cross sections for electron collisions with molecular clusters. The method is based on the calculation of accurate collisional information for the molecules constituting the cluster that is then combined to obtain a cross section for interaction with the whole system. Themethod provides a computationally cost-effectiveway of treating low energy electron scattering from (homogeneous and heterogeneous) molecular clusters and aggregates.Results for (H2O)n (n D 2,5) and (HCOOH)2 are presented; the cross sections agree well with more accurate ab initio data.
