Nuclides sorted by Half-Life

In reality so called Stable nuclides may are instable due to very long half-lifes and thus a radioactive decay was not experimentally observed until today. Therefore for those nuclides where no half-life is known, these are sorted by theoretically expected decay-mode and then by relative mass excess (column energy in the following list). Of course, this list must start with the primordial nuclides (up to and including position 288).

hint: 3.15576/cdot 10 sec = 1 year

decay mode legend

@ alpha-decay
- beta- decay
K electron capture
+ beta+ decay
F spontaneous fission
2 double beta- decay
Z double beta+ decay
I isomeric transition

list of nuclides

The colum labled "energy" denotes the mass of a nuclide for each nucleon in MeV relative to the mass of a neutron (so all nuclides gets a positive value)
