All data from [5].


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
