  An analysis of the asymmetric reactions $^{40,48}$Ca+$^{12}$C at 25 and 40
MeV/nucleon is presented. Data have been collected with six modules of the
FAZIA array. The analysis is focused on the breakup channel of sources produced
in dissipative collisions, partially corresponding to incomplete fusion
processes. The study has been performed both on detected fragments and on some
resonances reconstructed by means of particle-fragment correlations, with a
focus on the evolution of the breakup channel with the beam energy and the
neutron content of the system, looking in particular at the relative velocity
between the breakup fragments. Results show that also
  Carbon fragments reconstructed by means of particle correlations can be in
large part interpreted as the light partner of a scission.
