摘要：

Differential elastic electron-scattering cross sections of pyrimidine were absolutely measured for electron energies from 20 eV to 1 keV in the angular range between 5 degrees and 135 degrees. The present results agree with the data of other groups within the experimental uncertainties at scattering angles below 75 degrees while considerable differences among the data were found at higher scattering angles. The experimental values were compared to theoretical values calculated using the modified independent-atom model. The theoretical values reproduce the angular dependence of the experimental differential elastic scattering cross sections qualitatively well for electron energies above 60 eV. The sum of the integral elastic scattering cross sections, obtained by the integration of the differential elastic scattering cross sections, and ionization cross sections predicted by the binary-encounter-Bethe model agree with the previously measured total electron-scattering cross sections of pyrimidine to within 8%.
