We have measured cross sections for the ${}^{63}\mathrm{Cu}(\alpha ,\gamma ){}^{67}\mathrm{Ga}$ reaction in the $5.9-$ to $8.7-\text{MeV}$ energy range using an activation technique. Natural Cu foils were bombarded with α beams from the ${88}^{\text{'}\text{'}}$ Cyclotron at Lawrence Berkeley National Laboratory (LBNL). Activated foils were counted using a γ-spectrometry system at LBNL's Low Background Facility. The ${}^{63}\mathrm{Cu}(\alpha ,\gamma ){}^{67}\mathrm{Ga}$ cross sections were determined and compared with the latest NON-SMOKER theoretical values. Experimental cross sections were found to be in agreement with theoretical values.
