Low Energy Elastic Electron Scattering from Propyne-C$_{\mathrm{3}}$H$_{\mathrm{4}}$*

Experimental differential cross sections for electron scattering from gaseous C$_{\mathrm{3}}$H$_{\mathrm{4}}$ are presented. The measurements employed the relative flow method with a moveable aperture target gas delivery source [1], using helium [2,3] as standard. The moveable source enabled accurate determinations of background scattering [1]. The measurements were taken at incident electron energies of 1 eV to 30 eV and scattering angles of 10$^{\mathrm{o}}$ to 130$^{\mathrm{o}}$. Comparisons to any existing calculations will be made.
