provides information on the cosmic ray flux during the last fifty or so days before the meteorite struck the Earth. If one had a reliable estimate of the orbit of a freshly fallen meteorite, one could consider the meteorite to be a kind of space probe for cosmic rays.

(The production ratios listed in Table 1 for the irradiated targets are derived by correcting the observed activities to saturation levels, and should therefore be directly comparable with the extrapolated activity ratios in the meterorites exposed to cosmic rays only.) The Ar /Ar3' activity (or production)

Reynolds: We have some data, obtained accidentally, which supports your comment about production of Ar in low-energy reactions. In one of our pile irradiations of Richardton, the sample was placed in a large flux of fast neutrons, so that enough argon was formed for us to be able to see it on the mass spectrometer.
