【 摘 要 】

Synopsis We report measurements on differential cross sections (DCSs) for electron-impact excitation to the optically-allowed b1Πustate in molecular nitrogen in the impact energy range of 20 - 400 eV. Absolute excitation DCSs normalized by the relative flow technique were transformed to generalized oscillator strengths (GOSs) as a function of momentum transfer squared. Integral cross sections (ICSs) for the transitions to the b1Πustate were compared with the BEf-scaled plane-Born ICS as well as previous experimental studies.
