Isotopes of vanadium
From Wikipedia, the free encyclopedia

Naturally occurring vanadium (23V) is composed of one stable isotope 51V and one radioactive isotope 50V with a half-life of 2.71×1017 years. 24 artificial radioisotopes have been characterized (in the range of mass number between 40 and 65) with the most stable being 49V with a half-life of 330 days, and 48V with a half-life of 15.9735 days. All of the remaining radioactive isotopes have half-lives shorter than an hour, with the majority of them below 10 seconds. 5 metastable excited states have been found (including 2 for 60V).
The primary decay mode before the most abundant stable isotope 51V is electron capture or positron emission resulting in titanium isotopes; that after the beta decay to chromium isotopes.

- mV – Excited nuclear isomer.
- ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits.
- # – Atomic mass marked #: value and uncertainty derived not from purely experimental data, but at least partly from trends from the Mass Surface (TMS).
- Bold half-life – nearly stable, half-life longer than age of universe.
- # – Values marked # are not purely derived from experimental data, but at least partly from trends of neighboring nuclides (TNN).
- Modes of decay:
EC: Electron capture IT: Isomeric transition p: Proton emission - Bold symbol as daughter – Daughter product is stable.
- ( ) spin value – Indicates spin with weak assignment arguments.
- Order of ground state and isomer is uncertain.
