title: Experimental study of the cross-sections of alpha-particle induced reactions on 209Bi.
abstract: alpha-particle-induced nuclear reactions for generation of (211)At used in therapeutic nuclear medicine and possible contaminants were investigated with the stacked foil activation technique on natural bismuth targets up to E(alpha)=39 MeV. Excitation functions are reported for the reactions (209)Bi(alpha,2n)(211)At, (209)Bi(alpha,3n)(210)At and (209)Bi(alpha,x)(210)Po. Results obtained from direct alpha-emission measurements and gamma-spectra from decay products are compared and correspond well with earlier literature values. Thick target yields have been deduced from the experimental cross-sections and optimised production pathways for minimal contamination are presented. A comparison with the results of the theoretical model code ALICE-IPPE is discussed.
