Spalogenic rare gases in iron meteorites with anomalous silver

He, Ne, and Ar have been measured in seven iron meteorites for which anomalous Ag isotopic compositions were reported, in order to determine if ^(107)Ag excesses could be related to galactic cosmic-ray bombardment of these meteorites. Our results show that no correlation exists between ^(107)Ag excess and either the fluence or the energy spectrum of the particles producing spallogenic rare gases. Cosmic-ray-produced ^(107)Ag estimated from ^(38)Ar concentrations can account for only about 1% of the observed excess. Elimination of cosmic-ray bombardment as a production mechanism for ^(107)Ag excess strengthens the conclusion that the excess ^(107)Ag is the decay product of short-lived ^(107)Pd (τ_(1/2)=6.5Myr). The iron meteorite Piñon is shown to contain trapped rare gases with ^4He/^(20)Ne∼600.
