Average number of collisions to reduce neutron energy

Input(s)

$\boldsymbol{E}_{\boldsymbol{o}}$: Initial Energy Level (eV)

E: Final Energy Level $(\mathrm{eV})$

$\xi$: Average Energy Decrement per Collision (dimensionless)

Output(s)

$n$: Average Number of Collisions to Reduce Neutron Energy (dimensionless)

Formula(s)

$$ n=\left(\frac{1}{\xi}\right) * \ln \left(\frac{E_{o}}{E}\right) $$
