All data from [6].
| α: | alpha particle emission (4He nucleus) |
| β+: | emission of an anti-electron and a neutrino. A proton inside the nucleus is transformed into a neutron |
| β-: | emission of an electron and an anti-neutrino. A neutron inside the nucleus is transformed into a proton |
| ec: | electron capture: capture of one orbital electron by the the nucleus. A proton inside the nucleus is transformed into a neutron plus a neutrino |
| SF: | Spontaneous Fission: a nucleus spontaneously splits into fragment nuclides |
| IT: | Isomeric Transition: a level above the ground state decays via electromagnetic process |
| n: | neutron emission |
| p: | proton emission |
| β- n (and similar): | beta- decay followed by delayed neutron emission |
