Production of carrier-free radioisotopes from targets irradiated with deuterons or alpha particles in the U-120 Cracow Cyclotron

The results of experiments on the preparation of carrier-free lanthanides from some targets irradiated in the U-120 cyclotron are presented. In the reactions¹⁵¹Eu(α, n)^154m,154Tb,¹⁵¹Eu(α, 2n)¹⁵³Tb,¹⁵⁵Gd(α, 2n)¹⁵⁷Dy,¹⁶⁹Tm(α, n)¹⁷²Lu and¹⁶⁹Tm(α, 2n)¹⁷¹Lu, the isotopes^154m,154+153Tb,¹⁵⁷Dy and^172+171Lu were obtained. These were seaprated by means of ion-exchange chromatography. Part II: see Ref. 2
