Activation cross sections of proton induced nuclear reactions on palladium were measured up to 80 MeV by using the stacked foil irradiation technique and gamma ray spectrometry. The beam intensity, the incident energy and the energy degradation were controlled by a method based on flux constancy via normalization to the excitation functions of monitor reactions measured in parallel. Excitation functions for direct and cumulative cross-sections were measured for the production of 104m,104g,105g,106m,110m Ag, 100,101 Pd, 99m,99g,100,101m,101g,102m,102g,105 Rh and 103,97 Ru radioisotopes. The cross section data were compared with the theoretical predictions of TENDL-2014 and -2015 libraries. For practical applications thick target yields were derived from the measured excitation functions. Application in the field of medical radionuclide production is shortly discussed.

The (n, 2n) cross sections were measured for the nuclei N 14, pa, CalS, Sc4£ MnS~, NiSS, Cu6~, ZneS, Zn66, SeSZ, RbSS, RbST, ysa, Zra0, Mog.~, Snn2, Sm1~4 at ah excess energy 3 MeV above threshold. In addition, the (n, 2n) cross sections for the nuclei Zn s4, Zn 7~ Ga ea, Ga 71, As 75, Mo 1~176 Pb 2~ as well as the cross section of the process Pb ~~ (n, n') Pb 2~4m were determined at 14,7 MeV bombardirtg neutron energy. At 3 MeV excess energy a strong N-Z dependence has been found in the (n, 2n) cross sections, valid for a broad region of tteutron numbers which can be accounted for by the influence of direct inelastic scattering leading to low lying levels of the target rmcleus. An empirical formula is given for calculating (n, 2n) cross sections.

Abstract. In the frame of a systematic study activation cross sections of a few hundred deuteron induced reactions were measured up to 50 MeV on 25 metal targets having mostly natural isotopic composition. The majority of them have been measured for the first time. The recently measured data are still in the evaluation process. The experimental data were compared to the predictions of different theoretical codes. For better description developments of the theoretical models are in progress. The measured data find application in medical radioisotope production, thin layer activation and accelerator technology.
