Nuclear Transparency
Nuclear transparency can be defined as the ratio of cross-sections for exclusive processes from nuclei to those of the nucleons

If the nuclear cross-sections is denoted as $$\sigma_N$$ and free nucleon cross-section as $$\sigma_0$$ then nuclear transparency can be defined as

$$T= \sigma_N/A\sigma_0$$ ,where $$\sigma_N$$ can be parametrized in terms of $$\sigma_0$$ as $$\sigma_N =A^\alpha \sigma_0$$

Therefore transparency can be expressed as $$T= A^{\alpha -1}$$

Here nucleon cross-section can be think as hydrogen cross-section and nuclei cross-section can be as for other targets.
