Vanadium-68

Properties and data of the isotope ⁶⁸V.

Contents

Vanadium-68 is a radioisotope of the chemical element vanadium, which has 45 neutrons in its atomic nucleus in addition to the element-specific 23 protons; the sum of the number of these atomic nucleus building blocks results in a mass number of 68. The very short-lived, only artificially produced, unstable and thus radioactive nuclide has no practical significance; the study of ⁶⁸V is exclusively for academic purposes.

The discovery or first observation of the neutron-rich vanadium nuclide was first reported in 2025; accordingly, vanadium-63 was produced, separated, and identified by irradiating a carbon template with selenium-82 ions at an energy of 228 MeV/u [1].
