R. Zaman, S. Spellerberg, S.M. Qaim] For production of the medically interesting β+-emitter 55Co (T1/2=17.6h) via the 54Fe(d,n)-reaction, 91.6% enriched 54Fe2O3, mixed with Al powder, was pressed to a pellet which could be irradiated with 14MeV deuterons at 4µA in a water-cooled target system. A separation method was developed which led to >99.9% pure 55Co and allowed a recovery of the enriched target material. For a target thickness of Ed=12.6 → 5MeV, the experimental thick target yield of 55Co after chemical separation amounted to about 13MBq/µA·h, which is about 60% of the theoretical value. In a 3h irradiation at 4µA, the batch yield of 55Co achieved was 160MBq (4.3mCi). An 8h irradiation could lead to a batch yield of about 400MBq. The 54Fe(d,n) reaction leads to the highest purity 55Co but it is essential that the isotopic enrichment of the target is not less than 90%. In addition to the production work, cross sections were measured for the 54Fe(d,t) 53Fe and 54Fe(d,α)52mMn reactions using the standard stacked-foil technique and high-resolution γ-ray spectrometry. The cross section ratio for the isomeric pair 52m,gMn is discussed in terms of the spins of the two states involved and the increasing projectile energy. © 2003 Oldenbourg Wissenschaftsverlag GmbH Laboratory techniques, experiments nationallicence Analytical chemistry nationallicence Inorganic chemistry nationallicence Zaman M.
