Cosmic-ray produced rare gases have been measured in four meteorites with excess ^(107)Ag^* (Kelly and Wasserburg, 1978; Kaiser et al., 1980a, 1980b) to determine if ^(107)Ag^* is related to cosmic ray exposure. Kaiser et al. (1980a) considered the possibility that ^(107)Ag^* could derive from energetic particle reactions on Pd if the cross section times multiplicity for all reactions were ~ 10^2 b
