Abstract: | The mean lifetimes of negative molecular ions of C60 fullerene and its fluoroderivatives C60F18 and C60F36 with respect to the autodetachment of electrons have been measured as functions of the ionizing electron energy by the method
of mass spectrometry of electron resonance capture. The lifetimes of negative ions in the compounds under investigation are
within the one-second range, and an increase in the number of addends leads to an increase in the lifetimes of negative ions
by 1.5–2.5 orders of magnitude. |
