I apologize that me first post is such a silly one.(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to solve problem 1.2 in Stacey. It asks for the probability of a 1 MeV neutron slowing to thermal. I can determine the number of collisions required in the water / uranium environment. But, when I go to select the proper crosssections, I think I should just use scattering but I was wondering if fission is considered capture or noncapture?

Thanks, I really enjoy this forum...
