The strengths of resonances located at center-of-mass energies of Ec.m.=189, 304, 374, and 418 keV for the Mg25(p,γ) reaction have been measured for the first time with an off-line method: Mg targets were firstly activated with protons at the resonance energies and the produced Al26g nuclei were counted by means of highly sensitive accelerator mass spectrometry (AMS). Thus, the production of Al26 in its ground state is determined independently from the γ-decay branching ratio. While the 304, 374, and 418 keV resonances show fair agreement with previous measurements, the 189 keV resonance yield a significantly less strength. In addition, an experimental upper limit for the Ec.m.=92 keV resonance was determined.
