Electron scattering cross sections from HCN over a broad energy range (0.1–10 000 eV): Influence of the permanent dipole moment on the scattering process

摘要: We report theoretical integral and differential cross sections for electron scattering from hydrogen cyanide derived two ab initio potential methods. For low energies (0.1–100 eV), we have used the symmetry adapted-single centre expansion method using a multichannel formulation of problem. intermediate high (10–10 000 applied an optical based on screening corrected independent atom representation. Since HCN is strong polar molecule, further dipole-induced excitations been calculated in framework first Born approximation employing transformation to space-fixed reference frame K-matrix elements. Results are compared with experimental data available literature complete set recommended elastic, inelastic, total provided 0.1 10 000 eV.
