PROBLEMS
1. A 2MeV neutron is scattered elastically by 12C
through an angle of 45 degrees.
What is the scattered neutron's energy?
Solution:
From Eq. (6.25)
E' = ~
{JEcos(}s + VE(A2 1 + COS2
(}s)} 2
(A + 1)2
2. The first nuclear excited state of l~C is 4.439 MeV above the ground state.
(a) What is the Qvalue for neutron inelastic scattering that leaves 12C
in this
excited state? (b) What is the threshold energy for this scattering reaction?

Unformatted text preview: (c) What is the kinetic energy of an 8 Me V neutron scattered inelastically from this level at 45 degrees? Solution: (a) The Qvalue is computed as Q = {M(l~C) M(1~C*)}C2 = {Mr~C) [M(l~C) + E* jc2]}C2E* = 4.439 MeV. (b) From Eq. (6.15) l+~ ) Q=Mc 1 1+12 Eth n4.439) = 4.81 MeV. 61 July 24, 2002...
