Abstract: | This paper reports the determination of absolute excitation functions and cross section ratios for the production of 110(4.9 h)/110(69 min) In and108(58 min)/108(39.6 min)In in reactions of -particles with natural silver. Target stack foils of silver were bombarded with the 55.0 MeV -particle, beam available at the Buenos Aires synchrocyclotron. The -spectrometry was used for the identification and for the determination of the absolute activity of110(4.9 h)In and110(69 min)In from107Ag/, n/ and109Ag/, 3n/ reactions and of108(58 min)In and108(39.6 min)In from107Ag/, 3n/ and109Ag/, 5n/ reactions by means of Ge intrinsic detector.This work has been sponsored by the Subsecretaria de Ciencia y Tecnología Argentina. |
