Ne22p

Ne22p, also known as Neon-22, is a radioactive isotope of neon with a half-life of approximately 3.76 years. It is produced through the decay of sodium-22, which itself is a product of cosmic ray spallation of argon and other elements in the Earth's atmosphere. Ne22p is significant in the field of geochronology and cosmochemistry, as it provides valuable information about the age and origin of materials.

The primary decay mode of Ne22p is electron capture, resulting in the formation of stable fluorine-22. This decay process is accompanied by the emission of a characteristic gamma ray with an energy of 1274.5 keV. The presence of Ne22p in geological samples can be detected using accelerator mass spectrometry (AMS) or other sensitive analytical techniques.

Ne22p has been used to study various geological processes, including the age of groundwater and the duration of exposure of rocks to cosmic rays. Its unique properties and decay characteristics make it a valuable tool in the study of Earth's history and the dynamics of the solar system.
