Abstract
The differential cross section of the 18O(p, α)15N nuclear reaction has been calibrated at proton energies between 1700 and 1775 keV and at a detection angle of 155°. For the calibration, two silicon reference samples and a nickel sample were partially oxidized in enriched 18O. The absolute 18O-content in the grown oxide films is measured with RBS by direct comparison with a Bi-implanted silicon calibration standard. The measured resonance curve is fitted with a split Breit-Wigner function. The maximal cross section of the resonance at 1766 keV is found to be 135 ± 5 mb/sr. Its width is 4.5 ± 0.3 keV.
