Excitation functions of deuteron induced nuclear reactions on enriched 78 Kr with particular relevance to the production of 76 Br

Excitation functions of the Kr(d, α)Br, Kr(d, n)Rb and Kr(d, x)Kr reactions were measured for the first time in the energy range up to 13 MeV using the stacked gas cell technique and activation method. Highly enriched Kr was used as target material. The maximum cross section of the Kr(d, α)Br reaction at 13 MeV amounts to 21 mb and the calculated yield of Br over the energy range Ed = 13 → 4 MeV to only 59 kBq/μA h. Due to the very low expected yield of Br and the high cost of the target gas, this route is not suitable for production of Br compared with the other well investigated production routes.
