Excitation functions were determined by the stacked-foil and induced radioactivity measurement technique for the reactions 100 Ru(α,n) 103 Pd, 101 Ru(α,2n) 103 Pd, 101 Ru( 3 He,n) 103 Pd, and 102 Ru( 3 He,2n) 103 Pd, producing the therapeutic radionuclide 103 Pd, and for the reactions 101 Ru( 3 He,x) 101m Rh(Cum) and 102 Ru( 3 He,x) 101m Rh(Cum), producing the medically interesting radionuclide 101m Rh. Data were also measured for the reactions 101 Ru( 3 He,pn+d) 102m,g Rh, 102 Ru( 3 He,p2n+dn+t) 102m,g Rh, 101 Ru( 3 He,x) 101g Rh(Cum), 102 Ru( 3 He,x) 101g Rh(Cum), 101 Ru( 3 He,3n) 101 Pd, 102 Ru( 3 He,4n) 101 Pd, 101 Ru( 3 He,4n) 100 Pd, and 101 Ru( 3 He,p3n+d2n+tn) 100 Rh, producing other palladium and rhodium isotopes/isomers. The energy ranges covered were up to 25MeV for α-particles and up to 34MeV for 3 He ions. The radioactivity of the radionuclide 103 Pd induced in thin metallic foils of the enriched ruthenium isotopes was measured by high-resolution X-ray spectrometry and the radioactivities of other radionuclides by γ-ray spectrometry. The integral thick target yields of the radionuclide 103 Pd calculated from the excitation functions of the first four of the above-named reactions amount to 960, 1050, 50, and 725kBq/μAh, respectively, at the maximum investigated energies of the incident particles. The integral thick target yields of the radionuclide 101m Rh amount to 16.1 and 2.9MBq/μAh for 101 Ru and 102 Ru targets, respectively, at 34MeV energy of incident 3 He ions. The integral yields of the other observed radionuclides were also deduced from the excitation functions of the above-mentioned respective nuclear reactions. The excitation functions and integral yields of some rare reaction products were also determined. The experimental excitation functions of some reactions are compared with the predictions of nuclear model calculations. In general, good agreement was obtained.
