[en] The aim of the present investigation is to determine the entrance channel conditions to form nuclei as hot as possible and also to study their decay properties. The experiment has been realised at the GANIL facility using ¹⁴N, ⁴⁰Ar, and ⁵⁸Ni projectiles at intermediate energies and with beam intensities ranging from 100 to 500 nA. The technique we used to determine the linear momentum imparted to the target nucleus is the angular correlation of the fission products, whereas energies deposited in nuclei were deduced from the measurement of masses and velocities of both fission fragments. In summary, important amount of momentum transfers and excitation energies have been imparted to composite-like-nuclei with A approximately 270. A scaling for momentum transfer with the projectile mass is evidenced up to the Ni ions for central collisions. Velocity and size of projectiles play an important role as well as excitation energies deposited in fissioning nuclei, in fixing the central collision cross sections. Finally, high relative velocities of fission fragments have been measured and open an interesting problem on the fission properties of nuclei at high excitation energies and angular momenta
