All data from [7].
α:
alpha particle emission (
4
He 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
