Bremsstrahlung in the α-α and 3He-α Interactions
Abstract
The cross section of the bremsstrahlung process 4He(α,αα)γ has been measured at five energies between 11.4 and 13.5 MeV with detector lab angles of θ1=θ2=37∘, and at 9.35 MeV with θ1=θ2=35∘. The results agree well with predictions based on the work of Feshbach and Yennie, Signell, and Green. No significant enhancement is found at the final state energy corresponding to the 2.9 MeV resonance in 8Be. A single measurement of the process 4He(τ,αα)γ made at 7.4 MeV with θ1=θ2=37∘ is also in good agreement with theory. Details of the experimental technique and of finite geometry corrections are discussed. [NUCLEAR REACTIONS 3He-α and α-α bremsstrahlung, E=7.4,9.35,11.4-13.5 MeV, measured d2σdΩ1dΩ2.]
