CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishLow-energy (0-9 eV) electron capture by molecules of ortho- meta- and para-fluoronitrobenzenes has been investigated by means of electron attachment spectroscopy. 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.
