pääkonversion

Pääkonversion, also known as primary conversion, is a process in nuclear physics where a neutron is converted into a proton within the nucleus of an atom. This process is significant in the context of nuclear reactions and the behavior of neutron stars. In nuclear reactions, pääkonversion can occur through various mechanisms, including beta decay, where a neutron transforms into a proton, an electron, and an antineutrino. This process increases the atomic number of the element by one, effectively changing the identity of the atom. In the context of neutron stars, pääkonversion plays a crucial role in the star's cooling process and overall stability. As the neutron star ages, the pressure and temperature within the star can lead to the conversion of neutrons into protons, electrons, and neutrinos. This process, known as direct Urca process, is a significant contributor to the cooling of neutron stars. Understanding pääkonversion is essential for comprehending the life cycle of neutron stars and the fundamental properties of nuclear matter.
