The absorption expresses the total effect in X-Ray Mass Attenuation Coefficients 3. The Mass Energy-Absorption Coefficient, μ en /ρ The methods used to calculate the mass energy-absorption coefficient, μ en /ρ, are described perhaps more clearly through the use of an intermediate quantity, the mass energy-transfer coefficient, μ tr /ρ. The absorption coefficient µ a [cm-1] describes a medium containing many chromophores at a concentration described as a volume density a [cm 3]. The absorption coefficient is essentially the cross-sectional area per unit volume of medium. Molar extinction coefficient is measured in units of M^-1cm^-1.
