密度汎関数断裂力学に基づく断裂中性子の多重度の研究
The time evolution of the nuclear density of the fissioning system 240Pu during the scission process is obtained from the time-dependent superfluid local-density approximation (TDSLDA) to the density functional theory and a phenomenological dynamical scission model (DSM).
We find that multiplicity of scission neutron =1.347, i.e. half of the prompt fission neutrons measured in the reaction 239Pu(nth,f) are released at scission.
