The experiment has been carried out by using a vacuum ultraviolet radiation from a synchrotron source together with a time-of-flight spectrometer and a position sensitive ion detector. Isotopically labeled benzene molecules with a single deuterium atom have been used in order to study the symmetric dissociation of the benzene dication, not well evident in previous experiments. A threshold of 30.1 ± 0.1 eV has been observed for this dissociation reaction. Moreover, the lifetime of the dissociation of the benzene metastable dication producing CH3+ and C5H3+ has been obtained as a function of the photon energy, by the use of a Monte Carlo trajectory analysis of the coincidence distributions. The determined lifetime is independent of the photon energy and has an average value of 0.75 ± 0.22 μs. Theoretical calculations of the energy and structure of dissociation product ions have been also performed to provide crucial information about the dynamics of the charge separation reactions following the photoionization event.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-02-24T13:00:59Z No. of bitstreams: 1 http___scitation.aip.org_getpdf_servlet_GetPDFServlet_filetype=pdf&id=JCPSA6000135000014144304000001&idtype=cvips&doi=10.1063_1.pdf: 1484686 bytes, checksum: bf18ae8f521f1536c5a47e649e2a757e (MD5)Made available in DSpace on 2012-02-24T13:00:59Z (GMT).
