Fission neutron classification

  1. Jan 16, 2016 #1
    "Looking at time behaviour of neutrons in a reactor on time scales of both ~sec and ~days/months
    Start with fission process
    e.g. 235U + n -> 236U ->fission
    Usually divide into 2 Fission Fragments
    10%-20% of fission emit a scission neutron
    (i.e. at time of scission)"

    I've heard about prompt neutrons and delay neutrons, but what is scission neutrons?
    By means of scission I think it's prompt neutrons, but I don't think the yield of prompt neutrons is that low.
    Does any one know any thing about scission neutrons?
