Average Logarithmic Energy Decrement

Therefore the average energy of scattered neutron is taken as the average of energies with scattering angle 0 and 180 Moreover it is useful to work with logarithmic quantities and therefore one defines the logarithmic energy decrement per collision (ξ) as a key material constant describing energy transfers during a neutron slowing down ξ is not dependent on energy only on A and is defined as follows: For Get price
