Systematics of neutron emission probabilities from delayed neutron precursors

  • Published:
Zeitschrift für Physik

Abstract

A simple correlation based on the gross theory ofβ-decay is derived between the neutron emission probabilitiesP n of delayed neutron precursors, theirβ-decay energies and the neutron binding energies of the daughter nuclei. The correlation is shown to be valid for delayed neutron precursors among the fission products. TheP n-values of several expected but still unidentified neutron precursors are estimated together with their contributions to the delayed neutron groups in thermal-neutron induced fission of235U. Some aspects of theβ-strength function for transitions into highly excited states are discussed.
