Abstract

The ${}^{27}{Al}$ ( $n$ , $γ$ ) ${}^{28}{Al}$ 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 ${}^{28}{Si}$ transition following the $β$ decay of ${}^{28}{Al}$ was found to be 1778.987±0.015 keV.
