    In the present work we report on our experimental total cross section and positronium formation cross-section results for positron scattering from pyrimidine for energies from 1 to 180 eV. In addition, the total inelastic integral cross sections (for electronic excitations plus direct ionization) have been measured up to 21.5 eV. We also report quasi-elastic total and differential cross sections at energies up to 21.5 eV. Our results are compared to recent theoretical and experimental data for positron scattering, as well as recent work on electron scattering from this target.
