摘要：

In this work we report on a theoretical study on elastic electron collisions with ketenylidene radicals in the low and intermediate energy range. Calculated differential and momentum transfer cross sections for the e(-)-C2O collision are reported in the (1-500)-eV range. A complex optical potential composed by static, exchange, correlation-polarization plus absorption contributions, derived from a fully molecular wave function, is used to describe the interaction dynamics. The Schwinger variational iterative method combined with the distorted-wave approximation is applied to calculate scattering amplitudes. Comparison made between our calculated cross sections with the theoretical and experimental results for elastic e(-)-N2O collisions has revealed remarkable similarity for incident energies equal to 20 eV and above. Also, two shape resonances located at around 3 eV and 4.5 eV are observed and identified as due to the (2)Pi and the (4)Pi scattering channels, respectively.
