targets at four energies, 31, 35, 39 and 44 MeV/u, have been measured as well as the
energies, velocities and masses of both fragments. The characteristics of peripheral
collisions remain about constant in the range studied, whereas the component attributed to
the central collisions which shows a saturation in linear momentum transfer at 180 MeV/c
per incident nucleon, has a cross section decreasing with bombarding energy which is …
