Angular Distribution of Photoneutrons from Carbon and Beryllium

Abstract

The photoneutron angular distributions from carbon and beryllium have been measured by using bremsstrahlung of maximum energies of 23 Mev and 18 Mev, respectively. The results are $1+(1.35\pm 0.88){sin}^2\theta$ for carbon and $(1.26\mathrm{}\pm 0.11)+{sin}^2\theta$ for beryllium.
