摘要：

We present elastic integral (ICS), momentum transfer (MTCS) and differential cross sections (DCS) for low-energy positron and electron scattering by methylamine. The ICS and DCS results were obtained with the Schwinger multichannel method (SMC) for both projectiles. For the electron case only, we used the SMC version implemented with pseudopotentials. Our ICS results for electron scattering were compared with the experimental total cross section from [C. Szmytkowski, A.M. Krzysztofowicz, J. Phys. B 28, 4291 (1995)] showing reasonable agreement. We found a sigma* shape resonance at around 9.0 eV, which is close to the experimental value of 8.5 eV. We also compared our data for electron scattering with the ones obtained for positron scattering. To the best of our knowledge, there is no experimental data for positron-methylamine collision to compare against.
