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

Abstract

Deuteron induced reaction / Target element nat Kr / Stacked gas-cell technique / Excitation function / Thick target yield / 81 Rb( 81m Kr) generator Summary.A new route has been investigated for the production of the 81 Rb( 81m Kr) generator parent radionuclide at low energy cyclotrons. The excitation function of the 80 Kr(d,n) 81 Rb 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 81 Rb over the energy range E d ϭ 14 → 6 MeV amounts to 2.86 GBq/µA. A comparison of this production method with the commonly used 82 Kr(p,2n) 81 Rb route is given.

Development of novel positron emitters for medical applications: nuclear and radiochemical aspects

“…The suitable energy range, the thick target yield calculated from the excitation function, the expected radionuclidic impurities and the relevant references are given. For production, in general, solid targetry was used, except for the 38 Ar( p, n) 38 K, 78 Kr( p, α) 75 Br, 78 Kr(d, α) 76 Br and 82 Kr( p, n) 82m Rb reactions where gas targetry was employed. Technical development work has been performed in many institutes around the world but several of the radionuclides have been investigated only in one or two laboratories, with limited application.…”
