Stopping power for electrons in pyrimidine in the energy range 20-3000eV

4 pags.; 2 figs.; 2 tabs.In this work, we present new experimental electron energy loss distribution functions for pyrimidine (C4H4N2) measured for the incident energy range 30-2000eV. Theoretical total and elastic cross sections for electron scattering from pyrimidine were calculated using the screening-corrected additivity rule (IAM-SCAR) method. Based on the mean energy loss observed in the experiment and the theoretical integral inelastic cross section, the stopping power for electrons in pyrimidine is calculated in the energy range 20-3000eV. © 2013 Elsevier Ltd.h financial support of the Spanish Ministerio de Ciencia e Innovacio´n (Project FIS2009- 10245) and the EU Framework Programme (COST Action MP1002).
