Description
Investigation of the influence of angular momentum and the excitation energy of the compound nucleus on the Mass-Total Kinetic Energy (M-TKE) distribution of fission fragments give important insight into the fission process. The aim of the present work is to study the influence of compound nucleus angular momentum on the M-TKE distributions of fission fragments formed in the $^{24}$Mg + $^{232}$Th and $^{48}$Ca + $^{208}$Pb reactions, both the reactions leading to the formation of $^{256}$No$^*$ compound nuclei.
The experiments were carried out using the U400 cyclotron at the Flerov Laboratory of Nuclear Reactions, Dubna, Russia. Thin targets of $^{232}$Th and $^{208}$Pb bombarded with 125 - 181 MeV $^{24}$Mg and 208 - 281 MeV $^{48}$Ca beams, respectively, to populate the $^{256}$No$^*$ compound nuclei at different excitation energies. The mass-energy distributions of binary reaction products were measured by the double-arm time-of-flight (ToF-ToF) spectrometer CORSET [1]. In order to understand the influence of angular momentum of the compound nucleus on the M-TKE distribution, a detailed analysis has been carried out for the obtained M-TKE distributions.
