摘要：

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 A2' shape resonance in cyclopropane.
