Epithermal neutron diffusion coefficient

Input(s)

$L_{e}$: Slowing-Down Length $(\mathrm{cm})$

६: Logarithmic Energy Decrement Per Collision (dimensionless)

$\Sigma_{e}$: Macroscopic Scattering of Cross Section $\left(\mathrm{cm}^{2} / \mathrm{cm}^{3}\right)$

Output(s)

$D_{e}$: Epithermal Diffusion Coefficient (dimensionless)

Formula(s)

$$ D_{e}=\xi * L_{e}^{2} * \Sigma_{e} $$
