| Abstract: | A precision measurement of the Al27(n, α) Na24 — cross-section for 14.43 MeV was performed. Aluminium samples were irridiated in an accurately known neutron flux determined by the associated particle method. The induced Na24 activity was measured with a scintillation detector accurately calibrated by means of Na24 standards by the β-γ-coincidence method. By means of careful minimizing all sources of systematic errors an overall accuracy of 0.7% on a 99.5 (3 σ) confidence level was obtained. The measurements result in a cross-section of 117.0 mb for Al27(n, α)Na24 for neutrons of an average energy of 14.43 MeV and an energy width of approximately 0.2 MeV. |
