Figure 1: (a) Schematic illustration of the reaction mechanism. After fusion occurs between the ${}^{50}\text{Ti}$ beam and the ${}^{208}\text{Pb}$ target nuclei, the compound system almost always fissions into lighter components. Only in about one out of every $100$ million events is the end result ${}^{256}\text{Rf}$, which is produced when two neutrons evaporate. (b) Gamma-rays spectrum measured in the experiment.
