Abstract

The angular distribution of the photonuclear reaction3He(γ,p)2H was measured with an exitation energyE x=16 to 27 MeV using a 32.5 MeV betatron. In agreement with a theoretical calculation of Böschet al. we found for the coefficients of the distributionf(θ)=b (a/b+sin2θ(1+β·cosθ+γ·cos2θ)) the values:a/b≦0.14; β=0.77 (+0.14; −0.07); γ≦0.30. This was the first attempt to use spark chambers as a detection device for photonuclear reactions in the low energy range. We found it to be a promising new facility.
