Effects of Isospin on Multiplicity of Prescission Particles of Light Fissioning Systems

  • The isospin effect of particle emission for fissioning isobaric sources 110Tc,110Pd,110In and for isotopic sources of 110,117,124In were investigated within the framework of the Smoluchowski equation. Calculations show that the emission of prescission particles depends strongly on the isospin of the fission sources; With increasing isospin, neutron emission increases, but proton and α particle emission decrease; When a fissioning source has a larger isospin, light-charged particle emission is insensitive to the dissipation strength, indicating that for a light compound system with a high isospin, the multiplicity of proton and α particle is not a useful observable of extracting the magnitude of dissipation; The trend of various light particle emission with the isospin of fissioning systems is unrelated to the dissipation strength.

Abstract: The isospin effect of particle emission for fissioning isobaric sources 110Tc,110Pd,110In and for isotopic sources of 110,117,124In were investigated within the framework of the Smoluchowski equation. Calculations show that the emission of prescission particles depends strongly on the isospin of the fission sources; With increasing isospin, neutron emission increases, but proton and α particle emission decrease; When a fissioning source has a larger isospin, light-charged particle emission is insensitive to the dissipation strength, indicating that for a light compound system with a high isospin, the multiplicity of proton and α particle is not a useful observable of extracting the magnitude of dissipation; The trend of various light particle emission with the isospin of fissioning systems is unrelated to the dissipation strength.
