Linear absorption (attenuation) coefficient
Input(s)
\(\mathrm{N}\): Number of Atoms Per Unit Volume \(\left(\mathrm{m}^{-3}\right)\)
\(\sigma\): Thin Cross Section Expressed in Barns Per Atom \(\left(1\right.\) Barn Is \(\left.10^{-28} \mathrm{~m}^{2}\right)\left(\mathrm{m}^{2} /\right.\) atom \()\)
Output(s)
\(\alpha_{l}\): Linear Absorption Coefficient \((1 / \mathrm{m})\)
Formula(s)
\[
\alpha_{l}=\sigma * N
\]
