Types of radioactive decay

Decay type

The particles involved

Sub-core

The type of decay associated with nuclear emission:

Alpha Decay

The decay type of an alpha particle emitted in the nucleus (a = 4,z = 2)

(A ? 4,Z ? 2)

Proton emission

The decay type of a proton (p) emitted in the nucleus.

(A ? 1,Z ? 1)

Neutron emission

The decay type of a neutron (n) emitted in the nucleus.

(A ? 1,Z)

Dual Proton emission

A decay type that emits two protons simultaneously in the nucleus.

( A Span style= "Font-family:ms Mincho"? 2, Z 2)

spontaneous fission

Cluster decay

The nucleus emits a cluster of smaller nuclei or other particles of a specific type (a 1,Z 1)

(A ? A1,Z ? z1) + (A1,z1)

Various beta decay types:

Beta-decay

an electron is emitted from the nucleus (e ? ) and a decay type of a counter-electric neutrino (νe)

(A,z + 1)

Positron emission (β + decay)

The decay type of a positron (E +) and an electric neutrino (νe) emitted from the nucleus.

(A,z ? 1)

Electronic capture

The nucleus absorbs an orbital electron and emits a neutrino's decay type (the decaying nucleus exists in the form of an unstable excited state).

( A,Z ? 1)

double beta decay

( A , Z + 2)

Dual electron capture

The nucleus absorbs two orbital electrons and emits a decay type of two neutrinos (the nucleus of decay is unstable ??). the form of a stationary excitation state)

( A,Z ? 2)

Electron trapping associated with positron emission

The nucleus absorbs an orbital electron and then emits a positron and two neutrino decay type.

(A,Z? ) 2)

Double Positron emission

The decay types of two positron and two neutrinos emitted from the nucleus of an atom

( A,Z ? 2)

Conversion between nuclei of the same nucleus:

homogeneous heterogeneous conversion

Excited state nuclei emit high-energy photons (gamma rays) decay type

( A , Z )

internal conversion

Excited state nuclei transfer energy to orbital electrons, and the decay type of the orbital electrons from the atom

( A , Z )
