Photodisintegration

Photodisintegration (also called phototransmutation, or a photonuclear reaction) is a nuclear process in which an atomic nucleus absorbs a high-energy gamma ray, enters an excited state, and immediately decays by emitting a subatomic particle. The incoming gamma ray effectively knocks one or more neutrons, protons, or an alpha particle out of the nucleus. The reactions are called (γ,n), (γ,p), and (γ,α). Photodisintegration is endothermic (energy absorbing) for atomic nuclei lighter than iron and sometimes exothermic (energy releasing) for atomic nuclei heavier than iron. Photodisintegration is responsible for the nucleosynthesis of at least some heavy, proton-rich elements via the p-process in supernovae.This causes the iron to further fuse into the heavier elements.

What Are Neutron Stars?

When a dying star is too massive to leave behind a white dwarf and not massive enough to leave behind a black hole, you get a neutron star (sometimes a pulsar). It's a very compact clump of neutrons surrounded by a very strong magnetic field. These things are crazy!! ______________________

Exposure

When you take a photo, the sensor is exposed to light for a fraction of a second, or sometimes longer. The total amount of light that is captured is called the exposure. We hope you enjoy! To learn more, check out our written lesson here: https://edu.gcfglobal.org/en/digitalphotography/
