Electron’s antineutrino
from class: College Physics I – Introduction Definition An electron's antineutrino is an elementary particle with no electric charge and very little mass, emitted during beta decay. It is the antiparticle counterpart of the electron neutrino.
congrats on reading the definition of electron’s antineutrino . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test Electron's antineutrinos are produced in beta-minus decay when a neutron converts into a proton, an electron, and an electron's antineutrino. They have no electric charge and interact very weakly with matter, making them difficult to detect. Electron's antineutrinos are involved in conserving lepton number during nuclear reactions. Their existence was first hypothesized by Wolfgang Pauli in 1930 and later confirmed experimentally. The detection of electron's antineutrinos provides evidence for the conservation laws of energy and momentum in nuclear decays. Review Questions What role does the electron's antineutrino play in beta-minus decay? Why are electron's antineutrinos difficult to detect? How does the existence of an electron's antineutrino support conservation laws in nuclear physics?
