SILVER ISOTOPES PRODUCED BY ALPHA-PARTICLES ON RHODIUM

Excitation functions for the production of (105(m+g))Ag-106(m)Ag, from (alpha, xn) reactions on natural Rhodium were determined experimental ly in this paper. The method of activation of stacked metallic foils w as employed. The irradiations were performed in the Isochronous Cyclot ron at Karlsruhe (IK III/Zyclotron, Germany) with alpha-particles at 8 7 MeV. Gamma-spectrometry by with an intrinsic Ge detector was used to determine the produced nuclides. In addition, the yields of thick tar gets were calculated. In order to compare all the reactions (alpha, xn ) (x=1-4) on rhodium we used data from a previous work made at the Cyc lotron in Buenos Aires, where the excitation functions for the product ion of Rh-103(alpha, xn) Ag-107-x(x=1-4) were determinated, A comparis on between the experimental and the cross sections calculated using th e EXCLUSIVE INDEX model is presented.
