A neutron spectrometer is described which utilizes as a secondary ten trans-stilbene cylinders placed upon the circumference of a circle of 35-cm radius. These scintillators have a high efficiency coupled with low background- to-noise ratio. By this arrangement neutrons can be studied in terms of the proton recoil distribution produced within the scintillator. The spectrometer will record the spectra of gamma rays or neutrons depending on the amount of delay interposed between the primary and secondary signal. An angular distribution experiment performed with the neutron spectrometer is described, using the 0.72-Mev gamma resulting from the bombardment of Be with deuterons. The description of a linear gate circuit for pulse-height analyzers is also included. (J.R.D.)
