Nuclear transparency
Nuclear transparency is the ratio of cross-sections for exclusive processes from the nuclei to those of the nucleons.
If a nuclear cross-section is denoted as and free nucleon cross-section as,
then nuclear transparency can be defined as
, where can be parameterized in terms of as.
Therefore, transparency can be expressed as.
Here, nucleon cross-section can be thought of as a hydrogen cross-section, and nuclei cross-section can be as for other targets.
