Doubly charged ions C702+ were prepared in F+ (3 keV) + C70 → F + C702+ collisions. Up to seven successive evaporation of C2 have been observed in a time range of 1.7 μs. The dissociation energies of C70-2m2+ (m=1-7) were determined using a statistical cascade model to reproduce the excitation energy distribution of C702+ parent ions for each dissociation channel. Results are in good agreement with previous theoretical calculations. %G English %2 https://univ-lyon1.hal.science/hal-02313486/document %2 https://univ-lyon1.hal.science/hal-02313486/file/Br%C3%A9dy_2014_J._Phys.%20_Conf._Ser._488_102012.pdf %L hal-02313486 %U https://univ-lyon1.hal.science/hal-02313486 %~ CNRS %~ UNIV-LYON1 %~ ILM %~ UDL %~ UNIV-LYON
