Excitation functions for the formation of longer lived isotopes by deuteron irradiation of Europium

Excitation functions for nuclear reactions induced on natural europium targets by energetic deuterons were studied up to 50 MeV. A standard stacked foil technique was used for irradiation and high resolution gamma spectrometry was applied for activity assessment. Direct or cumulative cross sections for reaction products with half-life longer than 2 h were determined. Reactions leading to the formation of the radionuclides 147,149,151,153Gd, 147,148,149,150m,150g,152m,152g,154gEu, 153Sm and 150Pm were studied. In most cases no earlier data were available in the literature. The new experimental results were compared with values tabulated in the on-line TENDL2011 library.
