Abstract
A study of the gamma radiation following thermal-neutron capture by natural sodium and aluminum has been conducted using a Ge(Li) spectrometer. For sodium, 68 gamma rays were observed and their intensities and energies determined; for aluminum, 85 gamma rays were identified. A decay scheme for aluminum has been proposed from the present measurements. The neutron separation energies were found to be 6960.3 ± 1.5 keV for sodium and 7725.5 ± 1.5 keV for aluminum. The lifetime of the 472-keV level in sodium was measured to be 20.5 ± 0.5 ms using a chopped beam of neutrons.
