AB This thesis delves into nuclear fission, a complex process discovered in1939, exploring extreme deformations, nuclear structure effects, andheat flows influencing fragment distributions.The study focuses on fusion-induced fission in 265Db and 249Bk fissioningsystems generated with high excitation energies employing inversekinematics with the VAMOS++ spectrometer. Asymmetric fissionchannels are observed, providing insights into nuclear charge, mass,neutron excess, and neutron evaporation.In the case of 265Db, an overproduction of heavy fragments attributed toquasi-fission is observed. For 249Bk, the characterization of the scissionpoint is studied through crucial indirect observables for understandingnuclear structure effects, such as the total kinetic energy averagedbefore neutron evaporation.
