Title: Benchmarking nuclear fission theory

Abstract

We suggest a small set of fission observables to be used as test cases for validation of theoretical calculations. Thus, the purpose is to provide common data to facilitate the comparison of different fission theories and models. The proposed observables are chosen from fission barriers, spontaneous fission lifetimes, fission yield characteristics, and fission isomer excitation energies.

  • German) The concepts of fission theory developed in previous works (Ann. Physik (7) 7, 333(1961)) are systematically developed. From the basic conception of shell structure dependent deformation of the fragments at the moment of their separation, magic effects result in the nuclear force potential between both fragments and the mean kinetic energy of the fragments whose interaction makes quantitatively comprehensible the observed fission asymmetry. The spontaneous fission of Cf 252 is discussed as an example. The symmetric fission of Bi 209 (by deuterons) is described. A qualitative clarification is given of the known decrease in fission asymmetry with increased excitationmore » energy on the basis of the general hypotheses developed.« less
