The level structure of the ${}^{95}\mathrm{Nb}$ nucleus has been studied with the $(t,p)$ reaction in ${}^{93}\mathrm{Nb}$ using a tandem Van de Graaff accelerator and a multichannel magnetic spectrograph at an incident beam energy of 12 MeV. Proton spectra are obtained at 12 different angles from $5^{°}$ to ${87.5}^{°}$ at an interval of ${7.5}^{°}$. Measurements of the proton distributions from the ${}^{93}\mathrm{Nb}$$(t,p)$${}^{95}\mathrm{Nb}$ reaction were made for the ground and 54 excited states up to the excitation energy of 3.669 MeV. Absolute differential cross sections for the levels have been measured. The experimental angular distributions are compared with the theoretical distorted-wave Born approximation calculations to determine L values and $J^{\pi }$ values. The level structure of ${}^{95}\mathrm{Nb}$ is compared with previous results.
