Phys. Rev. 76, 611–613 (1949)The Angular Distribution of the Photo-Neutrons from BerylliumReceived 11 May 1949; published in the issue dated September 1949 The angular distribution of the photo-neutrons from beryllium has been studied for γ-ray energies of 1.70, 1.81, and 2.76 Mev. The distribution was found to be spherically symmetrical for the 1.70- and 1.81-Mev γ-rays. The 2.76-Mev gamma-ray yields a distribution of the form a+bsin2θ with a/b=1.2. © 1949 The American Physical Society URL:
