Bremsstrahlung inα−αScattering at 9.35 MeV

Abstract

A measurement of the $\alpha -\alpha$ bremsstrahlung cross section at 9.35 MeV has established the upper limit 5.1 ${\mathrm{\mu }\mathrm{b}/\mathrm{s}\mathrm{r}}^2$ with 90% probability. We give a comparison with predictions, including only single-scattering terms.
