Objective
The subject of this project is the multimodal character of nuclear fission. The distinct structures in fission fragment distributions, which are linked to vallley structures in the potential energy surface of a deformed nucleus, are nowadays called modes. It is known from previous work that the potential energy surface in fission depends on the nuclear composition and excitation energy of the fissioning compound. To provide a sound basis for theory, the systematics of mode population should be further investigated in experiment in order to establish the rules for the population of modes.
For this purpose a series of investigations will be done for the Cm-isotopes. These have barely been studied in the past but, from what is known, the mode structure in Cm seems to be prominent. A number of modern experimental facilities are necessary for obtaining reliable data. Cm isotopes will be studied at the time-of-flight spectrometer of the MEPhI (Moscow, Russia), at a multiparameter spectrometer for correlated fission fragments, neutrons and gamma-rays (Flerov Laboratory, Dubna, Russia) and at the ILL high flux reactor (Lohengrin mass separator). The technology for target preparation is available at the IPPE (Obninsk, Russia).
The key methodological idea is the comparative study of multidimensional spectra for the majority of observational variables in (nth,f) and (s,f) reactions for the largest feasible chain of isotopes. The reactions 243Cm(nth,f), 244Cm(s,f), 245Cm(nth,f), 246Cm(s,f) and 248Cm(s,f) will be studied.
