In ${}^{46}\mathrm{V}$ picosecond lifetimes were determined using the recoil distance Doppler-shift technique with the Cologne plunger device coupled to the EUROBALL IV spectrometer. The experiment was carried out using the ${}^{24}\mathrm{Mg}$(${}^{28}\mathrm{Si}$, $\alpha \mathit{pn}$) reaction at 110 MeV at the Strasbourg VIVITRON accelerator. Subsequently the differential decay curve method in coincidence mode was employed to derive lifetimes for four excited states in the $K^{\pi }=0^{-}$ band. The resulting transition probabilities give a comparison of isospin allowed and forbidden $E1$ transitions, which clarifies the decay properties of the $2^{-},T=0$ state. Furthermore the $B(E2)$ values within the $K^{\pi }=0^{-}$ band are discussed.
