## 4 Discussion and Conclusions  
The existing information on ternary fission has been mainly collected by studying the spontaneous and neutron-induced fission when the influence of shell effects are not damped by excitation energies. By studying nuclei in the region of masses around A = 250 large changes in mass and TKE distributions of binary decay products have been evidenced. These changes are related to the dynamical evolution of the processes. Also, the dynamical evolution of the ternary fission is still debated. The peculiarities of this region of nuclei, accessible in heavy-ion-induced reactions, due to the reduction of fission barriers could be favorable also for investigating the ternary fission.  
In this work, we have studied the kinematics of the possible decay processes of \({}^{248}\)Fm\({}^{*}\) compound nuclei produced in the \({}^{40}\)Ar + \({}^{208}\)Pb reaction at 230 MeV with the aim to define the observables to distinguish DTF, STF, and BF events.  
The fragments' energy and angular distributions have been calculated for the most probable ternary fragmentations chosen by the corresponding minima in TFP surfaces. It is found that by fixing the emission angles of the two heavier fragments the resulting energy and angular correlations are very different in DTF and STF processes. To define specific experimental conditions, the ternary fragmentation \({}^{132}\)Sn + \({}^{68}\)Zn + \({}^{48}\)Ca, corresponding to a minimum value in the TFP surface due to the two doubly magic products, has been considered. The comparative analysis of the products' angular and energy distributions has been considered for distinguishing the events originating from the different TF processes and symmetric and asymmetric binary fission events expected to be the main decay channels of the reaction. Thus, a multi-coincidence apparatus involving state-of-art detection elements, such as the TOSCA units and two-stage Si detector telescope array, has been proposed for collecting valuable data.  
The calculations filtered by implementing a realistic apparatus response function within the Geant4 simulation toolkit framework have been used to simulate the experimental observables. The simulation results indicate that binary and ternary fission events can be simultaneously measured and clearly separated by exploiting the differences in the energy, velocity, and angular distributions of the fragments.  
Regarding the estimated yields of TF, the efficiency of the proposed setup and the available beam intensity indicate the possibility of collecting valuable data by considering the systematics on \({}^{40}\)Ar-induced fission reactions. Then, in conclusion, the proposed experimental investigation seems to be well suited to evidence the TF in heavy-ion-induced reactions, determine the ratio between TF and BF occurrences, and progress in the knowledge of TF fission dynamics.  
We do not exclude the possibility that during ternary fission, neutrons can be produced. It would be useful to measure their multiplicities because the ternary neutrons can feed the cycles of reactions used for nuclear energy production and neutron transport as summarized in [78; 79].
