Vanadium-59

Properties and data of the isotope ⁵⁹V.

Contents

Vanadium-59 is a radioisotope of the chemical element vanadium, which has 36 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 59.

According to a report from 1985, the radioactive isotope was discovered during the fragmentation of Krypton-86 rays (33 MeV/u) [1].
