The average logarithmic energy decrement per collision, denoted by ξ (xi), represents the average reduction in the logarithm of neutron energy after a single scattering event in a moderator. It is defined as:

ξ=⟨ln⁡E0E1⟩\xi = \langle \ln \frac{E_0}{E_1} \rangle

where E0E_0 is the initial neutron energy and E1E_1 is the neutron energy _________ ________ _________ _____ __________ ______ _______ _________.
