Possibility of production of ⁸¹Rb via the ⁸⁰Kr(d,n) reaction at a small cyclotron

A new route has been investigated for the production of the ⁸¹Rb(^81mKr) generator parent radionuclide at low energy cyclotrons. The excitation function of the ⁸⁰Kr(d,n) ⁸¹Rb reaction was measured up to 14 MeV using natural Kr gas as target, the activation method and a stacked gas-cell irradiation technique. The saturation yield of ⁸¹Rb over the energy range E_d = 14 → 6 MeV amounts to 2.86 GBq/μA. A comparison of this production method with the commonly used ⁸²Kr(p,2n) ⁸¹Rb route is given.
