Abstract
A shell of neutron detectors was designed, constructed, and employed in γ-ray spectroscopy with Gammasphere. It consists of up to 35 tapered regular hexagons that replace the same number of forward Ge-detector modules in Gammasphere. The shell was designed for high detection efficiency and very good neutron-γ discrimination. The simultaneous use of time-of-flight, and two methods of pulse shape discrimination between neutrons and γ rays is described. Techniques for spectroscopy with efficient detection of two neutrons are discussed.
