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

Excitation functions of the ⁷⁸Kr(d,α) ⁷⁶Br, ⁷⁸Kr(d,n) ⁷⁹Rb and ⁷⁸Kr(d,x) ⁷⁹Kr 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 ⁷⁸Kr was used as target material. The maximum cross section of the ⁷⁸Kr(d,α) ⁷⁶Br reaction at 13 MeV amounts to 21 mb and the calculated yield of ⁷⁶Br over the energy range E_d=13→4 MeV to only 59 kBq/μA h. Due to the very low expected yield of ⁷⁶Br and the high cost of the target gas, this route is not suitable for production of ⁷⁶Br compared with the other well investigated production routes.
