Macroscopic Slowing Down Power
Although the logarithmic energy decrement is a convenient measure of the ability of a material to slow neutrons, it does not measure all necessary properties of a moderator. A better measure of the capabilities of a material is the macroscopic slowing down power. The macroscopic slowing down power (MSDP) is the product of the logarithmic energy decrement and the macroscopic cross section for scattering in the material. Equation (1-1) illustrates how to calculate the macroscopic slowing down power.
