Abstract A bremsstrahlung-photon difference method measurement of the Be/sup 9/( gamma ,n) cross section indicates maxima in the cross section of 1.15 plus or minus 0.15, 0.55 plus or minus 0.1, 1.2 plus or minus 0.2, and 1.0 plus or minus 0.3 mb at energies of 1.70, 2.40, 2.95, and 4.6 Mev, respectively. The angular distribution of the neutrons corresponding to the 1.70 and 4.6 Mev peaks is spherically symmetric; d sigma /d OMEGA = a + b sin/sup 2/ theta (a/b = 1.0 plus or minus 0.2) for the 2.95 Mev peak.
