Beta decay
In
nuclear physics
,
beta decay
(
ß
-decay) is a type of
radioactive decay
in which a
proton
is transformed into a
neutron
, or vice versa, inside an
atomic nucleus
. This process allows the atom to move closer to the optimal
ratio of protons and neutrons
. As a result of this transformation, the nucleus emits a detectable
beta particle
, which is an
electron
or
positron
.
