Electron Impact Ionization of Lithium
Journal of Research of the National Bureau of Standards, 1982 The electron impact ionization cross section of the neutral lithium atom has been calculated in a distorted wave exchange approximation. The total cross section is in good agreement with available experimental data at incident electron energies above 10 eV. Analytic fits are provided for the 1s and 2s subshell partial cross sections.

Excitation of electronic states in tetrahydrofuran by electron impact [PDF]
The Journal of Chemical Physics, 2011 We report on differential and integral cross section measurements for the electron impact excitation of the three lowest lying Rydberg bands of electronic states in tetrahydrofuran. The energy range of the present experiments was 15–50 eV with the angular range of the differential cross section measurements being 15°–90°.

Electron impact ionization of small molecules at intermediate energies: the molecular R-matrix with pseudostates method [PDF]
, 2005 A procedure for the ab initio study of electron–molecule collisions at intermediate energies is presented in detail. The molecular R-matrix with pseudostates method is based on the inclusion of discretized continuum states in the close-coupling expansion.

Methane Cluster Fragmentation by Fast Electron Impact
Atoms, 2023 We investigate the fragmentation of the CH4 cluster by fast electron impact at stagnation pressures from 0.5 bar to 16 bar. By measuring the time of flight spectrum (TOF), two types of ions, including (CH4)n−1CH5+ and (CH4)n−2(C2Hm)+, are observed.
