English

A sufficiently large and hot stellar core may generate gamma-rays energetic enough to initiate photodisintegration directly, which will cause a complete collapse of the core.

en.wikipedia.org

As neutron captures can proceed at any energy regime, neutron photodisintegration is unimportant except at higher energies.

en.wikipedia.org

More massive stars die by photodisintegration.

en.wikipedia.org

The initial collapse of degenerate cores is accelerated by beta decay, photodisintegration and electron capture, which causes a burst of electron neutrinos.

en.wikipedia.org

This causes the core to start to collapse as energy is taken away by photodisintegration, and the collapsing core leads to the formation of a black hole.

en.wikipedia.org

At these temperatures, photodisintegration (the breaking up of iron nuclei into alpha particles by high- energy gamma rays) occurs.

en.wikipedia.org

As the star reaches the end of its life, it reaches temperatures and pressures where photodisintegration's energy-absorbing effects temporarily reduce pressure and temperature within the star's core.

en.wikipedia.org

Photodisintegration is endothermic (energy absorbing) for atomic nuclei lighter than iron and sometimes exothermic (energy releasing) for atomic nuclei heavier than iron.

en.wikipedia.org

A less common form involves removing a neutron via photodisintegration.

en.wikipedia.org

The relevant mechanisms are neutron activation, alpha absorption, and photodisintegration.
