英文摘要We present a study of ionization and fragmentation of gaseous DNA base adenine induced by collision with 36 keV F2+ ions. Coincidence measurements between the outgoing projectiles F+, the recoil ions and the number of ejected electrons during the interaction have been performed. Charged adenine and its fragments mass distribution have been analyzed by time of flight spectrometry. The time of flight spectrum presents a peak of stable mono-charged adenine as well as the signature of an important fragmentation in mostly light charged fragments. Results have been interpreted as a function of the number of ejected electrons, which is related to the initial charge state of adenine before fragmentation. The coincidence spectrum between fragments provides information on some particular dissociation channels. (c) 2005 Elsevier B.V. All rights reserved.
