Everything about Beta Decay totally explained
In
nuclear physics,
beta decay is a type of
radioactive decay in which a
beta particle (an
electron or a
positron) is emitted. In the case of electron emission, it's referred to as "beta minus", while in the case of a
positron emission as "beta plus" .
Kinetic energy of beta particles has continuous spectrum ranging from 0 to maximal available energy (
Q), which depends on parent and daughter nuclear states participating in the decay. Typical
Q is of order of 1 MeV, but it can be from few keV to few tens MeV. The most energetic beta particles are ultrarelativistic, with speeds very close to the
speed of light.
decay
In decay, the
weak interaction converts a
neutron into a
proton while emitting an electron and an
antineutrino :
