Experimental scaling of plane-Born cross sections for the electron-impact excitation to the b1Πu state of N2 molecule

Abstract

SynopsisWe report measurements on differential cross sections (DCSs) for electron-impact excitation to the optically-allowed b1Πu state 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 b1Πu state were compared with the BEf-scaled plane-Born ICS as well as previous experimental studies.
