The 7Al(n, y)~Al reaction has been studied using curved crystal spectrometers, a pair spectrometer, and a Ge(Li) detector. Applying a self-consistent energy calibration, a set of 199 calibration energies relative to the 411 keV Au standard was obtained. An extensive level scheme up to 8 MeV has been established. The neutron binding energy was determined to be 7725.18+0.09 keV. The energy of the~i Si transition following the P decay of Al was found to be 1778.987+0.015 keV.
