Abstract:Dissociative electron attachment (DEA) and ion-pair dissociation (IPD) processes of Difluoromethane (CH2F2) have been studied in the incident electron energy range 0 to 45 eV. Three different fragment anions (F − , CHF − and F − 2 ) are detected in the DEA range and two anions (F − and CHF − ) are detected in IPD range. Absolute cross-section of the F − fragment ion is measured for the first time. Three different resonances for both F − and CHF − ions and one single resonance peak for the F − 2 ions are observ… Show more
