  The isotopic-yield distributions and kinematic properties of fragments
produced in transfer-induced fission of 240Pu and fusion-induced fission of
250Cf, with 9 MeV and 45 MeV of excitation energy respectively, were measured
in inverse kinematics with the spectrometer VAMOS. The kinematic properties of
identified fission fragments allow to derive properties of the scission
configuration such as the distance between fragments, the total kinetic energy,
the neutron multiplicity, the total excitation energy, and, for the first time,
the proton- and neutron-number sharing during the emergence of the fragments.
These properties of the scission point are studied as functions of the fragment
atomic number. The correlation between these observables, gathered in one
single experiment and for two different fissioning systems at different
excitation energies, give valuable information for the understanding and
modeling of the fission process.
