We report cross sections for the elastic scattering of electrons by the C3H6 isomers propene and cyclopropane from 5 to 40 eV. These results were calculated within the static‐exchange approximation, using the Schwinger multichannel method as implemented on the Touchstone DELTA distributed‐memory parallel computer. The integral elastic cross sections so obtained support recent observations of a substantial isomer effect in the total scattering cross section. Partial‐wave analysis indicates the presence of an unusual A′2 shape resonance in cyclopropane.
