Description

We have developed a gamma-ray detector system which is used in conjunction with a pulsed spallation neutron source to study fast neutron induced reactions. The detector system consists of five 7.6- x 7.6-cm bismuth germanate crystals that span an angular range from 450 to 1400 in the reaction plane. The sample is located 7.2 m from the neutron-production target. With this apparatus it is possible to simultaneously measure the excitation functions and angular distributions of reaction gamma rays in the neutron energy range from 1 to 100 MeV. Results on the 12C(n, n'γ=4.44 MeV) and 40Ca(n, γ0) reactions show the unique capabilities of this system. (orig.)
