Description

The activation curve of the 109Ag (γ, α) 105Rh reaction obtained with the betatron is presented. The already known activation curve of the 58Ni (γ, α) 57Ni reaction is used as intermediary. 105Rh is extracted by chemical separation. The 109Ag (γ, α) 105Rh cross section obtained is much greater than the one predicted by the statistical evaporation theory. Reprint of a paper published in 'Comptes rendus des seances de l'Academie des Sciences', T. 239, Sitting of August 2, 1954, p. 411-414.

Abstract (French)

Les auteurs presentent la courbe d'activation, obtenue au betatron, de la reaction 109Ag (γ, α) 105Rh. Ils utilisent l'intermediaire de la courbe d'activation de 58Ni (γ, α) 57Ni qui est connue. Le 105Rh est extrait par voie chimique. La section efficace de 109Ag (γ, α) 105Rh trouvee est beaucoup plus grande que ne le prevoit la theorie de l'evaporation statistique. Reproduction d'un article publie dans les Comptes rendus des seances de l'Academie des Sciences, T. 239, seance du 2 aout 1954, p. 411-414.
