The resonances of the reaction ²⁷Al(p, gamma )²⁸Si in the energy ran ge E_p = 0.7 to 2.1 MeV have been used to determine the calibration constant of a magnetic proton beam-energy analyzer very precisely. As well-defined calibration points the midpoints in the rise of thick-target resonance-yield curves were used. The calibration constant has been determined differentially, measuring the proton-energy differences between the resonances via de-excitation gamma -rays using a Ge(Li) detector. After the calibration constant was precisely determined, the absolute calibration energies of the resonances were obtained. The well-known 992 keV ²⁷Al(p, gamma )²⁸ Si resonance was determined to be 991.97 plus or minus 0.07 keV. The accuracy of the calibration energies obtained competes with the accuracy achieved using the absolute rf-cavity velocity gauge.
