We have produced the long-lived ground state of $^{92}\mathrm{Nb}$ by irradiation of niobium foils with 14.8-MeV neutrons, and we have established its half-life from measurements of the disintegration rate and the neutron fluence together with the known $^{93}\mathrm{Nb}(n,2n)^{92}\mathrm{Nb}^{g}$ cross section. On the basis of two separate experiments we obtain ${t}_{\frac{1}{2}}(^{92}\mathrm{Nb}^{g})=(3.6\ifmmode\pm\else\textpm\fi{}0.3)\ifmmode\times\else\texttimes\fi{}{10}^{7}$ yr.
