Radioactive Isotopes of Vanadium

Further consideration of the experimental facts concerning the active V of a half-life of 600 days leads to the conclusion that it should be attributed to ${\mathrm{V}}^{49}$ rather than to ${\mathrm{V}}^{47}$ as hitherto proposed. The relatively low yields of ${\mathrm{V}}^{50}$ in the ($d,n$) reaction and of ${\mathrm{V}}^{52}$ in the ($\alpha ,p$) reaction suggest the existence of not yet discovered long-lived isomers of these nuclei.
