Abstract

Calculations have been carried out to estimate the total fragment kinetic energies EK, total fragment excitation energies Ex, and approximate total number of neutrons ν emitted in the binary fission of heavy and superheavy nuclei. The kinetic energy calculations are based on a static scission model reported earlier for fissioning nuclei in the actinide region. The total energy release Q is calculated from a recent mass formula of Seeger, and the total excitation energy is obtained from the difference, Ex = QEK. The results show a strong peak in EK(A)[A = compound nucleus mass number] and a corresponding minimum in Ex(A), at A ≈ 264, corresponding to fission into two nearly double-magic (Z ≈ 50, N ≈ 82) fragments. Our predictions of EK, Ex, and ν disagree sharply with the liquid-drop predictions in the range 255 ⪅ A ⪅ 290. It appears from these results that kinetic energy measurements do not provide an unambiguous test for superheavy nuclei, while measurements of ν, if , seem to provide such a test.
