摘要: Absolute total non-dissociative and partial dissociative cross sections of pyrimidine were measured for electron impact energies ranging from 70 to 400 eV proton 125 up 2500 keV. MOs ionization induced by coulomb interaction studied measuring both through time flight mass spectrometry obtaining the branching ratios fragment formation via a model calculation based on Born approximation. The yields absolute as function energy combined with proved be useful tool determine vacancy population valence which several sets ions are produced. It was also key point distinguish dissociation regimes particles. A comparison previous experimental results is presented.
