Abstract

The only negative species observed at low energy are the NO2- fragment and the molecular anion. Both anion currents display two maxima associated with two distinct resonances. The effect of ample temperature on the dissociative electron attachment (DEA) cross section has also been investigated in the 80-200 °C range.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
