Search for scission neutrons using specific angular correlations in 235U fission induced by slow polarized neutrons

Finite difference approach for the two-dimensional Schrödinger equation with application to scission-neutron emission

“…We have considered a problem related to the nuclear fission, namely the emission of scission neutrons, an actual issue important for nuclear applications [2,[23][24][25][26][27][28]. Among the neutrons emitted during fission, one can distinguish chronologically three categories: The last two components form the large majority of fission neutrons and have been extensively studied.…”

“…The scission neutrons, emitted near the rupture point of the fissioning system, were less investigated, but are recently receiving an increasing attention. Estimated to represent 10-20% of the total number of neutrons, this kind of neutrons are considered responsible for important effects observed in the fission process [26][27][28] and are essential ingredients in numerical simulations. In order to study scission neutrons we have used the sudden approximation [29].…”

Investigation of neutron emission by n-n correlation function in fission process using an array detector

“…The experimental results concerning the emission of scission or pre-fission neutrons are rather contradictory due to some arbitrary assumptions made in various analyses. Recently, an approach dealing with fission induced by polarized neutrons has been proposed to solve this situation [1,2] exploiting the dependence between the neutron spatial orientation and the FF flight direction. This approach is extremely difficult mostly because of the reduced events statistics.…”
