Dependence of Isospin Effect in the Multiplicity of Pre-Scission Particles on the Angular Momentum

  • The influence of angular momentum in the context of isospin effects on the emission of different light particles for heavy fissioning isotopic sources of 189,202,212Po and for isobaric sources of 202Fr,202Po and 202Tl is studied within the framework of the Smoluchowski equation. Calculations show that the isospin effects on particle emission have a strong dependence on the angular momentum. Large angular momentum greatly weakens the influence of nuclear dissipation and isospin on particle emission. This means that to better extract dissipation strength with light particle multiplicities as a probe, it is important to select the compound systems with low spins, in addition to selecting a proper kind of particles for the systems with different isospins.

Abstract: The influence of angular momentum in the context of isospin effects on the emission of different light particles for heavy fissioning isotopic sources of 189,202,212Po and for isobaric sources of 202Fr,202Po and 202Tl is studied within the framework of the Smoluchowski equation. Calculations show that the isospin effects on particle emission have a strong dependence on the angular momentum. Large angular momentum greatly weakens the influence of nuclear dissipation and isospin on particle emission. This means that to better extract dissipation strength with light particle multiplicities as a probe, it is important to select the compound systems with low spins, in addition to selecting a proper kind of particles for the systems with different isospins.
