SCATTERING OF LONG WAVE-LENGTH NEUTRONS BY IRRADIATED BERYLLIUM OXIDE
Experiments were carried out on beryllium oxide specimens irradiated to three different doses. The results are plotted as ln(I/sub u//I/sub i/) versus wave length. The amount of extra scattering due to defects increases with neutron dose. For one set of specimens an annealing study was made by repeating the measurements after annealing the specimens at 200 deg C intervals from 200 to 1400 deg C. Two distinct effects, a decrease in attenuation near the Bragg cut- off, which anneals steadily from 200 to 1000 deg C, and an increase at longer wave lengths, which anneals between 1200 and 1400 deg C.
