摘要
We report theoretical studies of electron impact triple differential cross sections of two bio-molecules, pyrimidine and tetrahydrofurfuryl alcohol, in the coplanar asymmetric kinematic conditions with the impact energy of 250 eV and ejected electron energy of 20 eV at three scattering angles of -5 degrees, -10 degrees, and -15 degrees. Present multi-center distorted-wave method well describes the experimental data, which was obtained by performing (e, 2e) experiment. The calculations show that the secondary electron produced by the primary impact electron is strongly influenced by the molecular ionic multi-center potential, which must be considered when the low energy electron interacts with DNA analogues.
