Elastic Scattering of Low Energy Electrons from Acetonitrile (CH$_{\mathrm{3}}$CN).

Experimental differential cross sections for low energy electron scattering from acetonitrile, using the relative flow technique with helium [1], will be presented. The cross sections were taken at incident energies of 0.5 eV to 30 eV for scattering angles of 10$^{\mathrm{o}}$ to 130$^{\mathrm{o}}$ using a moveable aperture gas target source[1]. The results will be compared to the existing Schwinger multi-channel calculations of Maioli and Bettega [2]. [1] M. A. Khakoo, K. Keane, C. Campbell, N. Guzman and K. Hazlett, J. Phys. B: At. Mol.
