A Study of the Angular Distribution of Fragments in the Photofission of Uranium Isotope U233
The angular anisotropy of the fragments produced in the photofission of nuclei with odd atomic weights was studied in [1, 2], A dipole character was assumed for the absorption of the γ-quanta, and in all cases the yield ratio 1(θ = 90°)/I(θ = 0°) was measured, θ being the angle relative to the direction of the γ-ray beam. In view of the controversial role of the quadrupole absorption of γ-quanta in the photofission process, it was considered desirable to check the isotropy of the distribution for such nuclei over a wide angular range.
