•The energy transitions belong to the decay radiations of 75Ge and 69Ge which are the products of the photonuclear reactions of (γ,n) with germanium isotopes (75Ge and 69Ge) were measured with a high purity germanium detector.•A clinic linac was used to generate bremsstrahlung photons with 18 MeV endpoint energy.•The experiment consists of several parts including spectrums taken for original sample and the calibration data.•This type of experiment which has offline nature and not observing prompt transitions showed possibility of obtaining good results of energy transitions even with better precision. Photoactivation experiments have a wide range of application areas in nuclear, particle physics, and medical physics such as measuring energy levels and half-lifes of nuclei, experiments for understanding imaging methods in medicine, isotope production for patient treatment, radiation security and transportation, radiation therapy, and astrophysics processes. In this study, some energy transition values of the decay radiations of 75Ge and 69Ge, which are the products of photonuclear reactions (γ,n) with germanium isotopes (75Ge and 69Ge), were measured. The gamma spectrum as a result of atomic transitions were analysed by using a high purity semiconductor germanium detector and the energy transition values which are presented here were compared with the ones which are the best in literature. It was observed that the results presented are in agreement with literature in error range and some results have better precisions.
