Energy-loss studies on ion-pair formation reactions for the K + NO2 system

Abstract The energy loss spectra of K + ions produced in fast potassium atom—NO 2 molecule collisions were studied over the collision energy region 10–40 eV. The energy loss spectra for the K + NO 2 system showed five peaks. The first two peaks at about 3.0 eV are ascribed to the ground-states NO − 2 with vibrational excitation. The remaining three peaks are ascribed to the electronically excited states of NO − 2 .
