Volumetric photoelectric absorption cross section

Input(s)

$\rho_{e}$: Electron Density Index $\left(\mathrm{gm} / \mathrm{cm}^{3}\right)$

$P_{e}$: Effective Photoelectric Absorption Cross-Section Index (Barns per Electron)

Output(s)

U: Volumetric Photoelectric Absorption Cross-Section (Barns per Volume)

Formula(s)

$$ U=P_{e} * \rho_{e} $$
