SUMMARY
This discussion centers on the phenomenon of pair production in nuclear physics, specifically addressing why certain nuclei exhibit greater resistance to pair production than others. It is established that the pair production cross-section, which describes the likelihood of photon energy converting into an electron-positron pair, increases with atomic weight. Heavier nuclei are more capable of distributing energy among their nucleons, which contributes to their ability to absorb energy beyond the threshold required for pair production.
