Dissociation of doubly charged Coronene as a function of internal energy

Abstract : We report on the dissociation of doubly charged Coronene (C24H122+) as a function of internal energy. The mass spectra were obtained for internal energy measured up to 50 eV using the CIDEC method in collisions with F+ and H+ at 3 keV. The dehydrogenation processes of the molecule were observed over this large range of energy as well as the other weaker channels, loss of C2Hn, 2C2Hn and ionization. The branching ratios for the fragments C24H12-n2+, C22H12-n2+, C20H12-n2+ and C24H12-n3+ (n=0-6) were measured.
