Si28 + fast neutrons = -> ???

  1. May 8, 2017 #1
    When a target material is irradiated with neutrons, a number of nuclear reactions are possible. For the slow neutron activation of 28Si, 29Si is created. Determine what is created if 28Si is irradiated with fast neutrons. Then, consult the National Nuclear Data Centre (http://www.nndc.bnl.gov/nudat2/) and determine the gamma radiation that will be emitted.

    What is the energy of the most intense gamma peak?
    (assume the original target nuclei are those which are naturally most abundant)

    Similar to another post I just made. I read a little bit that said the reaction of Si28 and fast neutrons can create Al28. The fast neutron fuses with the Si nucleus, knocking out a proton, and then Al-28 decays back to Si-28 by emitting and gamma radiation.
