Fully microscopic scission-point model to predict fission fragment observables

NUCLEAR REACTIONS 235U, 239Pu(n, F), E=thermal; calculated proton density distribution, scission distance, Coulomb and nuclear interaction energies for the scission configuration of 236U into 104Mo and 132Sn, fission yields for four different estimates of the nuclear interaction energy and three proton densities at scission neck of 240Pu, pre-neutron-emission fission yields, kinetic energy (KE) distribution, fission yields for various neck densities, isotopic fission yields, proton odd-even effect amplitude for isotopic yields. Z=78-110, N=90-250; calculated peak multiplicities in the isobaric yields, mean TKE of fragments, mean available energy release per fission and mean prompt neutron multiplicity per fission, and mean deformation of fission fragments for about 2000 fissioning nuclei lying between proton and neutron drip lines from Pt to Mt for an initial excitation energy of 8 MeV. Z=91, N=125-200; Z=98, N=130-225; Z=106, N=145-240; calculated pre-neutron-emission isotonic yields and fragment deformation from fission of Pa, Ca and Sg isotopic chains with an excitation energy of 8 MeV. Calculations used upgraded version of scission-point yield (SPY2) model to estimate yields and the kinetic energy distributions of fission fragments, and using nuclear ingredients of 7000 nuclei at 120 axial quadrupole deformations, describing the fragments properties at the scission point.Comparison with available experimental data.

RADIOACTIVITY 252Cf(SF); calculated pre-neutron emission fission yields, fission yields for various neck densities, isotopic fission yields, kinetic energy per fragment, mean deformation, mean total kinetic energy, and proton odd-even effect amplitude for isotopic yields.
