ResumoHigh-spin states in $^{34}\mathrm{Cl}$ were populated in the $^{27}\mathrm{Al}(^{12}\mathrm{C}, \ensuremath{\alpha}n)^{34}\mathrm{Cl}$ fusion-evaporation reaction between 27 and 45 MeV incident energy and in the $^{31}\mathrm{P}(\ensuremath{\alpha}, n)^{34}\mathrm{Cl}$ reaction at 14.4 MeV. The decay scheme is obtained from $\ensuremath{\gamma}\ensuremath{-}\ensuremath{\gamma}$ and $n\ensuremath{-}\ensuremath{\gamma}$ coincidence measurements. The ${J}^{\ensuremath{\pi}}$ assignments for the levels at 4743, 4824, and 5315 keV result from angular distributions, directional correlation ratios, and excitation functions. The lifetime of the 5315 keV level was measured in a recoil distance experiment.NUCLEAR REACTIONS $^{27}\mathrm{Al}(^{12}\mathrm{C}, \ensuremath{\alpha}n)^{34}\mathrm{Cl}$; measured $\ensuremath{\gamma}\ensuremath{-}\ensuremath{\gamma}$ coinc and $\ensuremath{\sigma}(E\ensuremath{\gamma}, \ensuremath{\theta})$ at ${E}_{\mathrm{lab}}=40$ MeV and $\ensuremath{\sigma}(E)$ from 27 to 45 MeV; $^{31}\mathrm{P}(\ensuremath{\alpha}, n)^{34}\mathrm{Cl}$, ${E}_{\ensuremath{\alpha}}=14.4$ MeV, measured $n\ensuremath{-}\ensuremath{\gamma}$ coinc, $^{34}\mathrm{Cl}$ deduced levels, ${J}^{\ensuremath{\pi}}$.
