Elastic Low-Energy Electron Collisions with Methylamine

Abstract

We present ab initio scattering calculations results of low-energy electron collision with methylamine using $R$-matrix approach within the static-exchange (SE) and static-exchange-polarization (SEP) approximations. The elastic integral, momentum transfer and differential cross sections are reported. The calculated elastic integral cross sections are in agreement with the available experimental and theoretical data. A $σ^∗$ shape resonances of $^2A'$ symmetry located at 8.9 eV are detected within SEP model. For this dipole molecule Born-closure procedure was used to account for the higher partial waves $(l > 4)$ to obtain the convergence of the cross section.
