| x Double electron capture |
Double electron capture is a decay mode of atomic nucleus. For a nuclide (A, Z) with number of nucleons A and atomic number Z, double electron capture is only possible if the mass of the nuclide of (A, Z-2) is lower.
In this mode of decay, two of...

| x Cluster decay |
Cluster decay is a type of nuclear decay in which a radioactive atom emits a cluster of neutrons and protons heavier than an alpha particle. This type of decay happens only in nuclides which decay predominatly by alpha decay, and occurs only a small...

| x Double beta decay |
|
Double beta decay is a radioactive decay process where a nucleus releases two beta rays as a single process.
In double-beta decay, two neutrons in the nucleus are converted to protons, and two electrons and two electron antineutrinos are emitted. In...

| x Isomeric transition |
An isomeric transition is a radioactive decay process that occurs in an atom where the nucleus is in an excited meta state (e.g. following the emission of an alpha or beta particle). The extra energy in the nucleus is released by the emission of a...

| x Internal conversion |
Internal conversion is a radioactive decay process where an excited nucleus interacts with an electron in one of the lower atomic orbitals, causing the electron to be emitted from the atom. Thus, in an internal conversion process, a high-energy...

Potassium-40 | 10.67 % | 0 MeV |
Electron capture (sometimes called inverse beta decay) is a decay mode for isotopes that will occur when there are too many protons in the nucleus of an atom and insufficient energy to emit a positron; however, it continues to be a viable decay mode...

| x Spontaneous fission |
Spontaneous fission (SF) is a form of radioactive decay characteristic of very heavy isotopes. It is theoretically possible for any atomic nucleus whose mass is greater than or equal to 100 atomic mass units (u), i.e. elements near ruthenium. In...

| x Positron emission | Aluminium-26 | 82 % | 4.003 MeV |
Positron emission is a type of beta decay, sometimes referred to as "beta plus" (β). In beta plus decay, a proton is converted, via the weak force, to a neutron, a positron (also known as the "beta plus particle", the antimatter counterpart of an...

| x Neutron emission |
Neutron emission is a type of radioactive decay of atoms containing excess neutrons, in which a neutron is simply ejected from the nucleus. Two examples of isotopes which emit neutrons are helium-5 and beryllium-13. However, the decay of helium-5 is...

| x Proton emission |
|
Proton emission (also known as proton radioactivity) is a type of radioactive decay in which a proton is ejected from a nucleus.
Proton emission can occur from high-lying excited states in a nucleus following a beta decay, in which case the process...

| x Alpha decay | Gadolinium-152 | 100 % | 2.24 MeV |
Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, and thereby transforms (or 'decays') into an atom with a mass number 4 less and atomic number 2 less. For example:
An alpha particle is the same as a...

Sulfur-35 | 100 % | 0.1674 MeV |
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 is referred to as beta minus (β), while in the case of a positron emission as beta...
