Photodisintegration of the Deuteron at 20 Mev

Counter techniques have been applied to a study of the proton angular distribution in the photodisintegration of the deuteron induced by bremsstrahlung photons from a betatron in the energy interval 18-22 Mev. The measured distribution is given by $A+{sin}^2\theta (1+2\mathrm{}\beta cos\theta )$, with $A=0.132\mathrm{}\pm 0.041$ and $\beta \cong 0.1$. The total cross section is also measured.
