The radionuclides 73As, 88Y and 153Sm are of considerable significance in environmental and biological research as well as in internal radiotherapy. Cross section measurements related to the n.c.a. production of these radionuclides were carried out for the nuclear reactions natGe(p,xn)73As, natRb(α,xn)88Y and 150Nd(α,n)153Sm, using protons and alpha particles of energies up to 100 MeV and 26.5 MeV, respectively. The excitation function of the 150Nd(α,n)153Sm reaction has been measured for the first time. The existing nuclear database for the other two nuclides could be expanded and strengthened. In the case of 153Sm additionally the 153Eu(n,p)153Sm reaction cross section was measured averaged over a 14 MeV d(Be) neutron spectrum. The calculation of thick target yields was done and the production possibilities of the three radionuclides were evaluated.
