Abstract

Cascades of two successive γ-transitions following thermal neutron capture in 27Al have been studied. From γ − γ coincidences accumulated in the experiment, 13 intensity distributions of two-step cascades terminating at low-lying levels of 28Al have been determined. From these spectra, the energies of γ-transitions and intensities of 249 cascades populating 123 intermediate levels were derived. Energy dependence of intensity summed over the 0.5 MeV energy intervals for the cascades to two lower levels has also been determined.

Keywords
