The averaged fractional energy lost per elastic scattering event of neutron moderation process is shown in the following formulation \frac{\overline{\Delta E}}{E} = \frac{1}{2}(1 - \alpha) where $\overline{\Delta E} = E - \overline{E'}$, which is referring to the averaged energy lost after an elastic scattering event; $\alpha = \left(\frac{A - 1}{A + 1}\right)^2$, where A = M/m refers to the mass ratio of the target nuclide and a neutron. If the energy before scattering E = 5 × 10? eV, while the desired energy after \"moderation\" is 1 eV, how many collisions does a neutron required to encounter for such process, assuming this neutron always encounter elastic scattering interaction? Calculate the result assuming the target nuclides are ¹H and ¹²C. (atomic mass of ¹H is 1.007825; atomic mass of ¹²C is 12.00000).

12.38 Linear algebraic equations can arise in the solution of differential equations. For example, the following differential equa- tion derives from a heat balance for a long, thin rod (Fig. P12.38): $\frac{d^2T}{dx^2} + h'(T_a - T) = 0$ (P12.38.1) where $T_i$ designates the temperature at node $i$. This approximation can be substituted into Eq. (P12.38.1) to give $-T_{i-1} + (2 + h' \Delta x^2)T_i - T_{i+1} = h' \Delta x^2 T_a$ This equation can be written for each of the interior nodes of the rod resulting in a tridiagonal system of equations. The first and last nodes at the rod's ends are fixed by boundary conditions. (a) Develop an analytical solution for Eq. (P12.38.1) for a 10-m rod with $T_a = 20$, $T(x = 0) = 40$, $T(x = 10) = 200$, and $h' = 0.02$. (b) Develop a numerical solution for the same parameter values employed in (a) using a finite-difference solution with four in- terior nodes as shown in Fig. P12.38 ($\Delta x = 2$ m).
