Hello,
I just had a little debate with my professor after taking my final exam. He had given us an additional formula sheet at the last second (hand written on the projector) which confused me.
The question was a 7 MeV neutron collides with several U-238 atoms before reaching 2 MeV. How many collisions did it take to get there and what was the average loss.
So one of the equations he gave us was:
n = ln(E/E')/zeta
This equation confused me enough to screw up most of the problem. Afterward I looked it up and the correct equation is:
n = ln(E_1/E_2)/zeta
Which makes more sense to me but he argued they are the same thing. I am familiar with E' being elastic scattering with needs angles to solve (based on the formula sheet given to us) which is what messed me up.
Does my argument have a foundation?
