Abstract

The present article provides the first comprehensive study of electron scattering from the cyanoacetylene molecule. The results reported here include integral elastic cross-sections over a wide energy range (0.5 to 5000 eV) and differential, momentum transfer and electronic excitation cross-sections at low energies (<10 eV). For the computation of cross-sections over such a wide energy range, two formalisms are employed: the ab initio R-matrix method and the spherical complex-optical-potential method operating at low and high incident energies, respectively. The total ionization cross-section has also been calculated using the complex scattering potential-ionization contribution method and shows excellent agreement with previously reported values. The target parameters and resonance positions predicted by the R-matrix method are in reasonable agreement with, albeit limited, previous data. The resonances identified at low energies are associated to several dissociative electron-attachment channels.
