The production cross sections of 69Ga(n,p)69Znm, 69Ga(n,2n)68Ga, 71Ga(n,p)71Znm and 71Ga(n,2n)70Ga reactions at 14.77 ± 0.17 neutron energy and the bremsstrahlung spectrum averaged cross sections of 69Ga(γ,n)68Ga and 71Ga(γ,n)70Ga reactions at 15 MeV bremsstrahlung end point energy were measured using offline gamma spectrometry. Uncertainties in the measured cross sections were reported with a detailed covariance analysis. The experimental results were compared with previously reported experimental data from the EXFOR database and the evaluated nuclear data libraries ENDF/B-VIII.0, JENDL-5 and TENDL-2019. Theoretical nuclear model calculations were performed with the TALYS-1.95 code with default and optimized input parameters to fit with the experimental data. The measured cross sections were found to be in good agreement with the literature and theoretical calculations.
