“…It is known that Kr isotopes are important markers for the study of nuclear fission materials, so examining their features is important [22,23]. As seen from the figure, with increasing atomic mass of the fissile isotope of uranium, Kr spectra are shifted to the range of the neutron-rich nuclei and contain unstable fission fragments.…”

The first results about the features of the fission fragments yields and spectrum of the energy of fission over 100 isotopes of uranium are presented. The role of neutrons shells with N = 82 or N = 126 and protons shells with Z = 50 in the realization of symmetric (or onehumped) and asymmetric (2-or 3-humped) shapes of the fission fragment yields was investigated. It was shown that studies of Kr isotope yields under fission of uranium isotopes give also valuable information on the role of the mentioned nuclear shells, too. The obtained results can be useful in similar studies of other actinide nuclei.

The first results of the calculation of the mass and charge yields of fission fragments for over 60 isotopes which have Z = 118 are presented. The results were obtained from the condition of thermodynamic ordering of the ensemble of fission fragments. The role of neutrons shells with N = 82 or N = 126 and protons shells with Z = 50 in the realization of symmetric (or one-humped) and asymmetric (2-or 3-humped) shapes of the fission-fragment yields with the transition from neutron-proficient to neutron-deficient isotopes was investigated. The data of fragments yields had been analyzed under the conditions of a "cold" and "hot" fission. The calculations show the possibility to identify super-heavy nuclei with Z ≥ 118 produced synthetically by heavy-ion reaction on their mass/charge spectrum division.
