Schottky-like phase transition in the fission of atomic nuclei: U-235

摘要

Background: The physics of fission and the features of the fission fragment yields-symmetric or asymmetric shapes for different atomic nuclei and their energies of excitation or temperatures T-are among the "popular puzzles" of nuclear physics. Explanation of these features requires understanding both the nature of the interaction between the nucleons and the thermodynamics of nuclear matter transformations. The new statistical method for investigation of the ordering of the postscission ensemble of fission fragments is also essential.
