Where:
f
i
is the proportion of interaction
i
σ
i
is the cross section of interaction
i
per electron (the probability that the
incident photon makes an effect in the target element),
ρ
the density of the material target,
N
a
is the Avogadro number (6.023
23
/mol),
u
is the atomic mass unit, and
A
is the relative atomic mass of the target element
