Epithermal neutron distribution (epithermal neutron flux)

Input(s)

$N_{N}$: Source Strength (neutrons/s)

$\mathrm{r}$: Distance from Source $(\mathrm{cm})$

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

$D_{e}$: Epithermal Diffusion Coefficient $(\mathrm{cm})$

Output(s)

$\psi_{e}(r)$: Epithermal Neutron Flux at a Distance (r) from the Source (neutrons $/ \mathrm{cm}^{2} / \mathrm{s}$ )
