Neytron

Neytron (anglisi neutron, az lotini neuter — na inu na on, ishoratash p), zarrai elementarii khunso (bezaryad)-i massai sukunatash tp = = (1,674920±0,000011) • 10 kg, spinash 1/2/ (bo vohidhoi h =h/2P ), in jo h— sobitai Plank va momen­ti magnitiash Rt — — (1,91315±; 0,00007). Mya (Mya—magnetoni yadro). Neytronro olimi anglis Jeyms Chedvik kashf kardaast (1932). Yadroi hamai atomho az Neytronho va protonho tarkib yoftaast. Khosiyathoi Neytron va proton ba hamdigar monandand, ki dar baroba­rii spinhoshon, nazdik budani mas­sai sukunatashon, qobiliyati ba hamdigar mubaddalshaviashon (masalan, hangomi beta-kohish), hamchunin ba zaryad novobasta budani quvvahoi yadroi zohir megardand.

In khosiyatho imkon medihand, ki Neytron va protonro chun du holati (elektri zaryad­nok va bezaryad) yak zarra — nuklon muoina kunem. Neytron dar holati ozod noustuvor ast: on bo davri nimkohishi T1/2=(1,01±0,03).10e soniya ba proton, elektron na antineytrino judo meshavad. Neytronho ba cap zadani reaksiyahou yadroy, az on jumla, re­aksiyai zanjirii taqsimshavii yadrohoi vaznin (toriy, uran, pluto­niy), ki dar reaktorkhoi yadroi ba a mal meoyand, bois msgardad. Neytronhoro baroi hosil kardani izotophoi ra­dioaktivi suni va dar neytrono­grafiya istifoda mebarand. Antizarrai Neytron antineytron ast, ki az Neytron bo alomati momenti magnitiash farq mekunad.
